Custom Data Type

califa198

Hello,

I wanna know if its possible to make a custom data type. i would like to make a new data type for properties in which i can put 2 text fields for 1 data type, is this possible? where can i find information regarding this? it should be a data type just like d:text or d:datetime.

Anything would be useful, thanks

You could probably do this, but I think that would require some serious backend coding.

I'd discourage you from doing this - you can achieve the same effect by either creating an association to a content type with two text fields, or by storing the data as one text field, and creating a component generator that renders it as two fields to the user. Here is information about Component Generator framework.
http://wiki.alfresco.com/wiki/Component_Generator_Framework

In any case - here are the pages on Content Modeling:

Buffff!

I am interested in representing prices or other kind of precise decimal values in Alfresco.

I defined a custom data type mapped to java.math.BigDecimal in order to do so. I use it when defining a custom model and I configure the property sheets in the web-client to show it.

But when I try to use it in the web client the following problem arises:

11:54:20,476 ERROR [org.alfresco.web.ui.common.Utils] A system error happened during the operation: Property type not recognised:

At first I thougth it could be a problem with the component generator used for the UI, being it a new type it can't guess which one to use. So i explicitly configured the property so that it would be shown with TextFieldGenerator. But it didn't work.

In a second glance I noticed tha the error is thrown by org.alfresco.repo.domain.NodePropertyValue.makeValueType. This class seems to be related to the serialization of the properties in order to persist in the database.

To sum up this means that adding a new type is a really, really, really low level thing in Alfresco, so sadly jbarmash is completely right.

I'm going to use a double for now and in the midterm i might develop a custom component generator that eliminates the reamining decimals from the text input and that rounds the output value to the requested decimal numbers for the edition view.

It seems strange though that Alfresco hasn't this kind of data type available, or at least the component generator to "simulate it". Is there a good reason for this ?

billerby

I also gave up on this, when noticing some core classes seemed to be involved. My solution is to store it as cents/pennies in a long instead and use a converter for the gui-presentation.

iblanco

billerby could you please explain your solution a bit more extensively.
It would be a great help if you could show us some code also.

Thanks.

billerby

But of course

First in my model.xml file I declared my price property as of type d:long:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<property name="ac:resursPris">
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<type>d:long</type>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<mandatory>false</mandatory>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</property>
‍‍‍‍‍‍

In my web-client-config-custom.xml, when defning the propertySheet:

<show-property name="ac:resursPris" display-label-id="ac_smotModel.typ.ac_resurs.ac_resursPris" converter="PriceConverter"/>
‍‍‍

My converter class: (We will not need decimals in our gui)

package com.acando.alfresco.web.resurs;

import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.convert.Converter;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if (value == null){
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return "";
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// first lets divide the cents with 100 to get the amount in SEK with decimals
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;double convertedValue = longValue / 100;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// decimals should not be visible in gui, lets remove them.
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;int intMoney = (int)convertedValue;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return String.valueOf(intMoney);
&nbsp;&nbsp;&nbsp;}

}

Ok, last we need to make jsf aware of the converter, lets declare it in our faces-config-custom.xml

&nbsp;&nbsp; <converter>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <converter-id>PriceConverter</converter-id>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <converter-class>com.acando.alfresco.web.resurs.PriceConverter</converter-class>
&nbsp;&nbsp; </converter>
‍‍‍‍‍‍

iblanco

Thanks very much Erik.

I do need the decimals but I think that it will be quite easy to adapt your code for managing a couple of decimals. By the way, do you know if there is any way to pass a paramater to a converter ? That would allow to use a common converter for all kind of decimal representations just by saying how many decimals there are.

Thanks very much.

billerby

iblanco,

It seems that you can provide properties by defing them in faces-config, found an example:

<converter>
<converter-id>numberConverter</converter-id>
<converter-class>br.com.softcomex.components.gui.presentation.converters.NumberConverter</converter-class>
<property>
<property-name>maxFractionDigitsMask</property-name>
<property-class>java.lang.Integer</property-class>
</property>
</converter>

It works like a charm (as far as I have tested it). You can set the number of digits that will be considered the decimal part. But I have not been able to especify the number of fractions to use in the web-client config.

This is my faces-config-custom.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE faces-config PUBLIC "-//Sun Microsystems, Inc.//DTD JavaServer Faces Config 1.1//EN"
                              "http://java.sun.com/dtd/web-facesconfig_1_1.dtd">
<faces-config>
   <converter>
      <converter-id>PriceConverter</converter-id>
      <converter-class>es.binovo.alfresco.web.ui.repo.converter.Long2DecimalConverter</converter-class>
      <property>
         <property-name>fractionDigits</property-name>
         <property-class>java.lang.Short</property-class>
      </property>
   </converter>
</faces-config>‍‍‍‍‍‍‍‍‍‍‍‍‍

If i do not specify the "property" element it takes by default 2 fraction digits and it works fine, but if I include the "property" element I am not able to specify it in the web-client configuraction and it gets automatically 2 digits for the fraction (useless). This is the corresponding part of my web-client-config-custom.xml file:

   <config evaluator="node-type" condition="eun:ofertaProyecto">
      <property-sheet>
         <show-property name="eun:descuentoOferta" display-label="Descuento" converter="PriceConverter" fractionDigits="3"/>
         <show-property name="eun:portesOferta" display-label="Portes" converter="PriceConverter" fractionDigits="3"/>
         <show-property name="eun:tipoIvaOferta" display-label="Tipo IVA" converter="PriceConverter" fractionDigits="3"/>
         <show-property name="eun:formaPagoOferta" display-label="Forma de pago" />
         <show-property name="eun:plazoEntregaOferta" display-label="Plazo de entrega" />
         <show-property name="eun:validezOferta" display-label="Valido hasta" />
      </property-sheet>
   </config>
‍‍‍‍‍‍‍‍‍‍‍‍

Alfresco (Community 3.0.0 Stable) does not complain at all but it just uses 0 fraction digits. Is there a way to do it or simply Alfresco is unable to receive parameters for the converter ?

If it is impossible I guess I'll have to extend the class for each use case, horrible and hackish but it surely works.

I have opened a new topic to discuss this.

[Offtopic]: By the way, how do I grant some points to the helpful replies in the forum ?

billerby

Nice to see you got an (almost) working converter (no parameters). I think the points system is constructed in the way that only the author of the thread can give points for helpful replies.

/Erik - still without points

iblanco

The converter works but the components validation is not locale aware, so if I don't write the numbers in english the validation does not post the changes, and if I'm using Alfresco in Spanish, as my converter is locale aware does not interpret the number right.

That is quite discouraging and strange, I can't believe that nor Alfresco nor anyone in the community is using Alfresco with fixed precision numbers in a language other than english.

I suppose I have 3 options:

- Forget Locale awareness.
- Create my own component.
- Represent all numeric values as Strings and build a converter in order to manage locale related conversions my own.

The first one sucks, as Alfresco is supposed to be locale aware for most of things.
The second one seems complex.
The third one seems not very efficient, but its quite easy. The problem is that probably there won't be the possibility to validate data correctnes before posting.

I don't know what to do, I might give a go to the second one.

iblanco

I extended the standard TextFieldGenerator:

public class NumberLocaleAwareTextFieldGenerator extends TextFieldGenerator {

   private static Log logger = LogFactory
         .getLog(NumberLocaleAwareTextFieldGenerator.class);

   @Override
   protected void setupConstraints(FacesContext context,
         UIPropertySheet propertySheet, PropertySheetItem property,
         PropertyDefinition propertyDef, UIComponent component) {

      // if the property type is a number based type and the property
      // sheet is in edit mode and validation is turned, on add the
      // validateIsNumber validation function
      if (propertySheet.inEditMode() && propertySheet.isValidationEnabled()
            && propertyDef != null) {
         // check the type of the property is a number
         if (propertyDef.getDataType().getName().equals(
               DataTypeDefinition.DOUBLE)
               || propertyDef.getDataType().getName().equals(
                     DataTypeDefinition.FLOAT)
               || propertyDef.getDataType().getName().equals(
                     DataTypeDefinition.INT)
               || propertyDef.getDataType().getName().equals(
                     DataTypeDefinition.LONG)) {
            List<String> params = new ArrayList<String>(5);

            // Get the current locale
            Locale locale = context.getViewRoot().getLocale();
            DecimalFormatSymbols symbols = new DecimalFormatSymbols(locale);
            char decimalSeparator = symbols.getDecimalSeparator();
            char thousandSeparator = symbols.getGroupingSeparator();

            if (logger.isDebugEnabled()) {
               logger.debug("Preparing number validation for locale " + locale + 
                     " with decimal separator '" + decimalSeparator 
                     + "' and thousand separator '" + thousandSeparator +"'.");
            }

            // add the value parameter
            String value = "document.getElementById('"
                  + component.getClientId(context) + "')";
            params.add(value);

            // add the validation failed message to show
            String msg = Application.getMessage(context,
                  "validation_is_number");
            addStringConstraintParam(params, MessageFormat.format(msg,
                  new Object[] { property.getResolvedDisplayLabel() }));

            // Tell Javascript about locale related separators
            addStringConstraintParam(params, String.valueOf(decimalSeparator));
            addStringConstraintParam(params, String.valueOf(thousandSeparator));

            // add the validation case to the property sheet
            propertySheet.addClientValidation(new ClientValidation(
                  "validateIsLocalisedNumber", params, false));
         }
      }
   }
}
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

And added a couple of new functions to validation.js:

/**
 * Function taken from:
 *     http://simonwillison.net/2006/Jan/20/escape/ 
 */
function regexp_escape(text) 
{
   if (!arguments.callee.sRE) {
       var specials = [
         '/', '.', '*', '+', '?', '|',
         '(', ')', '[', ']', '{', '}', '\\'
       ];
       arguments.callee.sRE = new RegExp(
         '(\\' + specials.join('|\\') + ')', 'g'
       );
     }
   return text.replace(arguments.callee.sRE, '\\$1');
}

/**
 * Ensures the value of the 'control' is a number
 * as specified by the supplied locale related separators.
 * 
 * @return true if the value is a number
 */
function validateIsLocalisedNumber(control, message, decimalSeparator, thousandSeparator, showMessage)
{
   var result = true;
   
   var decimalRegexp = new RegExp("^[-]?([0-9]*|[0-9]{1,3}(" 
         + regexp_escape(thousandSeparator) + "[0-9]{3})*)" 
         + "(" + regexp_escape(decimalSeparator)  + "[0-9]+)?$");
   var value = control.value;
   
   if (!decimalRegexp.test(value)) {
      informUser(control, message, showMessage);
      return false;
   }   
   return true;
}
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

This works, but seems quite hackish for a such a simple thing….

billerby

To make it less hackish, I would generate the JavaScript in your component instead of modifying an Alfresco core file, avoiding the need to repatch when upgrading Alfresco.

/Erik

iblanco

You are right Erik:

I'm trying to do it but I do not know very well how to do it. I have tried overriding the createComponent method of the textFieldGenerator:

   @Override
   protected UIComponent createComponent(FacesContext context,
         UIPropertySheet propertySheet, PropertySheetItem item) {
      ResponseWriter out = context.getResponseWriter();
      if (propertySheet.inEditMode()) {
         try {
            if (logger.isDebugEnabled()) {
               logger.debug("Including custom validation JavaScript file.");
            }
            out.write("\n<script type='text/javascript' src='");
            out.write(context.getExternalContext().getRequestContextPath());
            out.write("/scripts/custom/validation.js");
            out.write("'></script>\n");            
         } catch (IOException e) {
            if (logger.isErrorEnabled()) {
               logger.error("Unable to include custom validtaion JavaScript file.");
            }
            if (logger.isDebugEnabled()) {
               logger.debug(e);
            }
         }
      }
      UIComponent component = super.createComponent(context, propertySheet,
            item);
      return component;
   }
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

But this approach has a serious problems, the script file is included as many times as the generator is called (once per each property using the generator). It works, but It seems at least horrible or problematic.

It seems like the proper place to include this scrip tag would be "UIPropertySheet" class but I suppose I would have to do a complete new generator in order for it to use the extended version of the UIPropertySheet. I can't find an easy way to add the script in a "once by request/page render" way.

Is it possible, at all? Any suggestion? Thanks.

iblanco

I've got it

It's not the nicest way on the world of doing it, but its less hackish, it works and it doesn't touch Alfresco's core classes.

I used the HTML separator offered by Alfresco and incrusted the required Script through it including the separator in the property page (only in edit mode)

faces-config-custom.xml has:
