URGENT HELP !!! showing the association as a hyperlink

hey123

Hello,
I am defining a new content type with a child content association. But, when I want to view the properties of an object of this content type, child associations are shown like below:

Incoming Documents:      /company_home/README.txt
                                     /company_home/11111111README_mysql.txt
(not a hyperlink, just the text version of the xpath of the documents)

But I want to make these association contents (can be text or jpeg files) viewable when I click on them.

Thank you in advance,

My Model Definition:
<type name="my:iadeDosyasi">
         <title>Standard Operating Procedure</title>
         <parent>cm:content</parent>
          <properties>
           <property name="my:EvrakNumarasi">
               <type>d:text</type>
            </property>
</properties>
         <associations>
            <child-association name="my:gelenEvraklar">
               <source>
                  <mandatory>true</mandatory>
                  <many>false</many>
               </source>
               <target>
                  <class>cm:content</class>
                  <mandatory>false</mandatory>
                  <many>true</many>
               </target>
            </child-association>
        </associations>
      </type>
My Web Client Configuration :
<config evaluator="node-type" condition="my:iadeDosyasi">
      <property-sheet>
     <show-property name="my:EvrakNumarasi" />

Hi,

I've been also trying to link documents but couldn't find out how to view them as links instead of xpath. I don't know if this could be done only by configuring xml files, maybe that would suppose modifying interface.
I'll be watching this topic.

gavinc

Basically the generic child association editor is being used. This can be overridden by using the component-generator attribute in the config file, however, you need to create a custom component generator.

Have a look at the following wiki pages as a start:

http://wiki.alfresco.com/wiki/Displaying_Custom_Metadata
http://wiki.alfresco.com/wiki/Component_Generator_Framework

Once you have an idea of how to go about it, you'll need to create a component that shows whatever is at the end of the child association i.e. an image when the component is in read-only mode.

Hi Gavinc,
I looked at the wiki pages.
At the end, I decided to use NodePath component of alfresco and I created a generator for it. Steps that I took were:

1-I created a jar file including the following source code

package org.alfresco.web.bean.generator;

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

import org.alfresco.web.app.servlet.FacesHelper;
import org.alfresco.web.ui.repo.RepoConstants;
import org.alfresco.web.ui.repo.component.property.PropertySheetItem;
import org.alfresco.web.ui.repo.component.property.UIPropertySheet;

/**
* Generates a component to manage child associations.
*
* @author gavinc
*/
public class CustomNodePathGenerator extends BaseComponentGenerator
{
   private String disabled;

   public UIComponent generate(FacesContext context, String id)
   {
      UIComponent component = context.getApplication().
            createComponent("org.alfresco.faces.NodePath");
      FacesHelper.setupComponentId(context, component, id);
      component.getAttributes().put("disabled", this.disabled);
      return component;
   }

   @Override
   protected void setupMandatoryValidation(FacesContext context, UIPropertySheet propertySheet,
         PropertySheetItem item, UIComponent component, boolean realTimeChecking, String idSuffix)
   {
      // Override the setup of the mandatory validation
      // so we can send the _current_value id suffix.
      // We also enable real time so the page load
      // check disables the ok button if necessary, as the user
      // adds or removes items from the multi value list the
      // page will be refreshed and therefore re-check the status.

      super.setupMandatoryValidation(context, propertySheet, item,
            component, true, "_current_value");
   }

public String getDisabled() {
   return disabled;
}

public void setDisabled(String disabled) {
   this.disabled = disabled;
}
}

2-Then I add the following lines to faces-config-custom.xml

<managed-bean>
   <managed-bean-name>CustomNodePathGenerator </managed-bean-name>
   <managed-bean-class>org.alfresco.web.bean.generator.CustomNodePathGenerator</managed-bean-class>
   <managed-bean-scope>request</managed-bean-scope>
   <managed-property>
      <property-name>disabled </property-name>
      <value>true</value>
   </managed-property>
</managed-bean>

3-Then I add the following lines to web-client-config-custom.xml
<show-child-association name="my:incomingDocuments" component-generator="CustomNodePathGenerator" display-label="Incoming Documents"/>

But nothing happened.

Even I tried each of the followings:

<show-child-association name="my:incomingDocuments" converter="org.alfresco.faces.DisplayPathConverter" component-generator="CustomNodePathGenerator" display-label="Incoming Documents"/>

<show-child-association name="my:incomingDocuments" converter="org.alfresco.faces.DisplayPathConverter" display-label="Incoming Documents"/>
And again I got nothing. Can you help me please.

Thank you in advance.

gavinc

When you say nothing happens what do you mean?

Do you see the association at all i.e. the default component? Are there any errors reported? Remove the comment for the line "#log4j.logger.org.alfresco.web.ui.common.Utils=info" in log4j.properties and try displaying the property sheet again.

However, this component was not designed to work within the property sheet and has therefore not been tested in this configuration so I'm not sure whether it's going to work, it may well be relying on some context that is not available within the property sheet.

hey123

Nothing changed in the child association part,
while waiting for your answer, to understand whether there is a problem in showing this new generator in the property sheet, I tried using this generator for a text area field, and then the property sheet could not show it, so you are probably right that it is giving error messages in the background.

Sir,
as a result, just to show the text in hyperlinks do I have to write a new component ?

And if this is the only solution, can you advice me a preexisting component to just copy, paste and make as little as possible changes to reach the result.

Thank you very much for your previous quick response. I am trying to finish this for a very important demo to our clients.

Hopefully that client will want to pay for support 🙂

Urgent help from the core engineers via the forums is asking them to be very nice to you! They only get their salaries from the paid support that people take out.

Cheers
Paul.

hey123

We were trying to sell(not actually sell you know getting support training etc.) alfresco to them

,
anyway I will say in the demo that, this is just a trial version and at the end they will be able to see the documents.

Thanks.

Unfortunately, yes, it looks like you'd need to write a new component to achieve the result you need.

The component you tried to use probably has the code in it you'd need to generate the link. Just follow the pattern for any other self rendering component, for example, UINodeWorkflowInfo.

couldn't we use the actionLink defined here ?

hey123

Hi,
in fact I don't know whether this works, I will look into action links.
I solved my problem not by writing a new component, but by changing the alfresco source code of related component, namely UIChildAssociationEditor. If you need it you can also change it, or if you want I may send it to you.

Have a nice day.

Hi,
Sounds weird that we have to all this fuss just to show the path as a link.
Yes it would be very nice if you could sent it to me, or tell me which files you changed/added.
Thanks a lot and have a nice day.

Hello,
this is the file that I changed,
but please note that since this was just a demo, I solved the problem in a quick and dirty way, i.e. by just adding the "http://...vs" line. (hardcoded)
So it needs more work.

Thanx for your code. Btw did you use SVN for developing ? Because I'm currently working with SDK, I wondered if it was possible to develop easily component generators, because deploying with SVN takes a lot of time…

hey thank you so much, I finally managed to make it work.
have a nice day.

Can someone please tell me where I could find UIChildAssociationEditor.java so I can replace it with the one here on the forum. I did a search for it but couldn't find it. I use Alfresco 2.0 Enterprise Edition, if that is any help.

Hope you can help me out, thanks!!

frederick

While trying to do the same thing (making child-associations clickable in the property sheet), I noticed that the UIChildAssociation class ignores overridden "component-generator" attributes (RepoConstants.GENERATOR_CHILD_ASSOCIATION is used instead).
The UIProperty class on the other hand does allow overriding of this attribute (this.getComponentGenerator()).

Is there any chance that the "component-generator" attribute will be overridable for show-association and show-child-association tags as well in a future release?

Since my project must be packaged as a module, I cannot alter the UIChildAssociationEditor class, nor can I override the managed bean ChildAssociationGenerator or the component org.alfresco.faces.ChildAssociationEditor.

gavinc

Hi,

You are indeed correct, the association editors do not pick up the component generator specified in config. I have raised an improvement on JIRA for this: http://issues.alfresco.com/browse/AWC-1174. So yes, it should get done in a future release.

Meanwhile, you should still be able to override this. What you'll need to do is override the managed bean definition for "ChildAssociationGenerator". You can re-define the managed bean with your class in the faces-config-custom.xml file as mentioned in http://wiki.alfresco.com/wiki/Packaging_And_Deploying_Extensions. This file is located in WEB-INF so you should be able to include this in your module. The file that is present by default is empty so it's OK to overwrite it (MyFaces needs a file to be present so we had to supply an empty one).

Hope this helps.

Hi everybody !

I'm trying to make my own model too with a chil-association rendered as a link.
However I didn't manage to make it work.

I have created my CustomNodePathGenerator, put the needed properties in the configuration files as follow (I have my own packages) :

<managed-bean>
<managed-bean-name>ChildAssociationGenerator</managed-bean-name>
<managed-bean-class>com.test.web.bean.generator.CustomNodePathGenerator</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
<managed-property>
<property-name>disabled </property-name>
<value>true</value>
</managed-property>
</managed-bean>

In  web-client-config-custom.xml
<show-child-association name="my:auteurs" component-generator="CustomNodePathGenerator" /> ‍‍‍‍‍‍‍‍‍‍‍‍‍

I have then created a new UIChildAssociationEditor still in my own package (com.test.web.ui.repo.component.property) with the file version of Alfresco 2.0.

In faces-config-custom.xml I have added :

<component>
      <component-type>com.euriware.test.web.bean.generator.CustomNodePathEditor</component-type>
      <component-class>com.euriware.test.web.ui.repo.component.property.UIChildAssociationEditor</component-class>
   </component>‍‍‍‍

And in web-client-config-custom.xml :

<show-child-association name="my:auteurs" component-generator="com.euriware.test.web.bean.generator.CustomNodePathGenerator"/>‍

When I run Alfresco and I try to see the details, I have the following error :

I don't understand where the problem is. Could you please help me ?

serv

Hello again !

I have tried to put my UIChildAssociationEditor in the web-client.jar within the WEB-INF/lib folder.
However, I still have the same error. In conclusion, the package is not the problem… Any other idea ?

gavinc

Does your implementation of UIChildAssociation extend BaseAssociationEditor?

The ClassCastException you are getting suggests that it's not!

serv

My UIChildAssociation class does actually extend BaseAssociationEditor.

I have solved my problem by adding the UIChildAssociation.class in the web-client.jar within the WEB-INF/lib folder with the right package (org.alfresco.web.ui.repo.component.property).
I have then modified the method generate of CustomNodePathGenerator.java as follow :

public UIComponent generate(FacesContext context, String id) {
      UIComponent component = context.getApplication().createComponent(RepoConstants.ALFRESCO_FACES_CHILD_ASSOC_EDITOR);
      FacesHelper.setupComponentId(context, component, id);
      logger.error("CustomNodePathGenerator generate "+component.toString());
      return component;
   }‍‍‍‍‍‍

Now, it works well.
