Problem with Custom Aspects

vpps

Hi,

I'm somewhat new to Alfresco and have been familiarizing myself with the wiki, forum and Packt book.

Now Iâ€™m trying to create a custom aspect for which Iâ€™ve modified the following files in the alfresco/extension folder:
â€¢   custom-model-context.xml
â€¢   customModel.xml
â€¢   and web-client-config-custom.xml

But on restarting the Alfresco server, when I try to create a business rule in the webclient UI, in the Create Rules Wizard â€“ Set action values, I do not see the newly created custom aspect to set as a rule.

I tried the example-model-context.xml, exampleModel.xml and web-client-config-custom.xml, but it still did not work.

Could you suggest as to what the problem could be….

Thanks,
Padma

Would it help if I provided extracts of the custom-model-context.xml, customModel.xml and/or and web-client-config-custom.xml ?

Please advice.

This would be a great help, since I'm waiting on this to complete a prototype with Alfresco, so as to leverage the work on future client projects.

Just noticed that the section in the web-client-config-custom.xml was commented out somewhere earlier in the file….

Wish I'd noticed it earlier….

Anyway, sorry about that.

Have you modified your web-client-config-custom.xml as below ?

   <config evaluator="aspect-name" condition="prefix:nameOfAspect">
      <property-sheet>
         <show-property name="prefix:metadata1"/>
         <show-property name="prefix:metadata2"/>
         <show-property name="prefix:metadata3"/>
         <show-property name="prefix:metadata4"/>
      </property-sheet>
   </config>

   <config evaluator="string-compare" condition="Action Wizards">
      <aspects>
         <aspect name="prefix:nameOfAspect"/>
      </aspects>
   </config>

   <config evaluator="string-compare" condition="Advanced Search">
      <advanced-search>
         <content-aspect>
            <aspect name="prefix:nameOfAspect" />
         </content-aspect>
         <custom-properties>
            <meta-data aspect="prefix:nameOfAspect" property="prefix:metadata1" />
            <meta-data aspect="prefix:nameOfAspect" property="prefix:metadata2" />
            <meta-data aspect="prefix:nameOfAspect" property="prefix:metadata3" />
            <meta-data aspect="prefix:nameOfAspect" property="prefix:metadata4" />
         </custom-properties>
      </advanced-search>
   </config>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

The most important part for you is the second config's node. Hope that will help you.

I've completed the 1st two sections in the web-client-config-custom.xml, namely the following (after which I'm able to create a business rule using the custom aspect in the web client):

<config evaluator="aspect-name" condition="prefix:nameOfAspect"> 
      <property-sheet> 
         <show-property name="prefix:metadata1"/> 
         <show-property name="prefix:metadata2"/> 
         <show-property name="prefix:metadata3"/> 
         <show-property name="prefix:metadata4"/> 
      </property-sheet> 
   </config> 

   <config evaluator="string-compare" condition="Action Wizards"> 
      <aspects> 
         <aspect name="prefix:nameOfAspect"/> 
      </aspects> 
   </config> 

‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

The above appears to link the aspect properties such that the aspect and the properties appear in the web client while creating a business rule on the aspect.

Regarding the last section, could you clarify as to why this is required or what it does:

<config evaluator="string-compare" condition="Advanced Search"> 
      <advanced-search> 
         <content-aspect> 
            <aspect name="prefix:nameOfAspect" /> 
         </content-aspect> 
         <custom-properties> 
            <meta-data aspect="prefix:nameOfAspect" property="prefix:metadata1" /> 
            <meta-data aspect="prefix:nameOfAspect" property="prefix:metadata2" /> 
            <meta-data aspect="prefix:nameOfAspect" property="prefix:metadata3" /> 
            <meta-data aspect="prefix:nameOfAspect" property="prefix:metadata4" /> 
         </custom-properties> 
      </advanced-search> 
   </config>

I am having the same issue you described. Have resolved this issue yet? I followed the examlpe in Alfresco Book from chapter 7. Alfresco boots with no errors, but I don't see my custom aspect.

priyanka_nayak

Hi ,
While adding a new aspect in custommodel.xml like in the code below, I am getting exception : org.alfresco.service.cmr.dictionary.InvalidAspectException: The aspect is invalid: {custom.model}CustomerDetails

My code is:
<aspects>
<aspect name="custom : CustomerDetails">
<title>Customer Details</title>
<properties>
<property name="custom : CustomerName">
<title>Customer Name</title>
<type>d:text</type>
</property>
<property name="custom : CustomerContactName">
<title>Customer Contact Name</title>
<type>d:text</type>
</property>
<property name="custom : CustomerProjectID">
<title>Customer Project ID</title>
<type>d:int</type>
</property>
</properties>
</aspect>
</aspects>

Plez reply bac…Its very urgent..
Regards,
Priyanka

Hello,

Seems there are blank spaces around the : in your property names.

priyanka_nayak

Even if i reply blank spaces its giving the same exception..

dhalupa

Could you post entire model definition and enclose it with "code" tags in order to be more readable?

Kind regards,

Denis

Edited by moderator to enclose XML in code tags. Please remember to use the Code tags when posting code on the forum. Thanks.

dhalupa

You did not close namespace tag properly, besides that I did not found anything wrong. Try pasting model below..

no its still not working…can you just tell me whether there are any other files other than the three where the changes are to be made..

fhomasp

If I'm not mistaken you'll need to define a model first and then the aspect. I declared the model after the namespace declaration and I enclosed the model in the <types> modelstuff</types> tags.

<types>
&nbsp;&nbsp; 
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <!– Definition of new Content Type: Real CV –>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <type name="rls:cv">
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <title>Real CV</title>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <parent>cm:content</parent>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <properties>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <property name="rls:name">
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <type>d:text</type>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </property>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </properties>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <mandatory-aspects>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <aspect>cm:versionable</aspect>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <aspect>rls:locatable</aspect>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </mandatory-aspects>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </type>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
</types>

<!–aspect definitions go here–>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I don't think you need mandatory aspects, but you need a type defined between the types tag.

Hope it helps

priyanka_nayak

Hi everybody,
