Hi all,

I don't know if this is the appropiate forum, but I'll give it a shot…


I'm trying to develop a Custom Action following the steps that I've founded in the wiki:

Custom ActionsCustom Action UI

So, taking these guidelines into account, I've created the following files:

[size=150]01_tagsModel.xml[/size] [located at 'WEB-INF/classes/alfresco/extension' folder]

<?xml version="1.0" encoding="UTF-8"?>

<!– Definition of new Model –>
<model name="tag:tagsmodel" xmlns="http://www.alfresco.org/model/dictionary/1.0">

   <!– Optional meta-data about the model –>   
   <description>Tagging Model</description>
   <author>Gavin Cornwell</author>
   <version>1.0</version>

   <!– Imports are required to allow references to definitions in other models –>   
   <imports>
      <!– Import Alfresco Dictionary Definitions –>
      <import uri="http://www.alfresco.org/model/dictionary/1.0" prefix="d"/>
      <!– Import Alfresco Content Domain Model Definitions –>
      <import uri="http://www.alfresco.org/model/content/1.0" prefix="cm"/>
   </imports>

   <!– Introduction of new namespaces defined by this model –>
   <namespaces>
      <namespace uri="extension.tags" prefix="tag"/>
   </namespaces>
  
    <aspects>
      
      <!– Definition of new Taggable Aspect –>
      <aspect name="tag:taggable">
         <title>Taggable</title>
         <properties>
            <property name="tag:tags">
               <title>Tags</title>
               <type>d:text</type>
               <multiple>true</multiple>
            </property>
         </properties>
      </aspect>
      
   </aspects>
   
</model>

And I have an ext-action-tag.jar file at 'WEB-INF/lib' containing:
dit»alfresco»ext»action»executer»TagActionExecuter.class
dit»alfresco»ext»action»executer»01_tag-action-messages.properties

where the java file is:

package dit.alfresco.ext.action.executer;

import org.alfresco.repo.action.executer.*;
import org.alfresco.service.cmr.repository.*;
import org.alfresco.service.cmr.action.Action;
import org.alfresco.service.cmr.action.ParameterDefinition;
import org.alfresco.service.namespace.QName;
import java.util.List;

public class TagActionExecuter extends ActionExecuterAbstractBase
{
      public static final String NAME = "tag";

      private NodeService nodeService;

      public void setNodeService(NodeService nodeService) 
      {
         this.nodeService = nodeService;
      }
      
      @Override
      public void executeImpl(Action action, NodeRef actionedUponNodeRef){
         if (this.nodeService.exists(actionedUponNodeRef) == true){
            // add the aspect if it is not already present on the node
            QName tagAspect = QName.createQName("extension.tags", "taggable");
            if (this.nodeService.hasAspect(actionedUponNodeRef, tagAspect) == false){
               this.nodeService.addAspect(actionedUponNodeRef, tagAspect, null);
            }
         }
     }
      
      @Override
      protected void addParameterDefintions(List<ParameterDefinition> paramList){
         //there are no parameters
      }
}

but I'm always getting this error message when creating the bean and I don't know why:

Can anyone give some advice, please?
I really need your help.

Hi,

From sight there seems to be nothing wrong with the code and the config.

Looking up the meaning of the error on Google I get ..

'Thrown when an application tries to call an abstract method. Normally, this error is caught by the compiler; this error can only occur at run time if the definition of some class has incompatibly changed since the currently executing method was last compiled.'

I'd suggest double checking for compile errors when constructing the jar and ensureing that the jars you are comiling against are the same as those in the runtime environment.

Perhaps a unit test (see those in the repository code for examples) will help to prove that your action is working and this is a deployment issue.

Cheers,
Roy
