Hi, I'm trying to execute javascript every time file updated at wcm webproject.I'm trying to add custom javascript behaviour to trigger update of content in AVM store.I've added bean like this:<bean id="onUpdateDoc" class="org.alfresco.repo.policy.registration.ClassPolicyRegistration" parent="pol

By default content policies aren't fired for modifications to AVM content. You can enable it by adding the following bean definition to a custom Spring *-context.xml file in ${ALFRESCO_HOME}/tomcat/shared/classes/alfresco/extension:


<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE beans PUBLIC '-//SPRING//DTD BEAN//EN' 'http://www.springframework.org/dtd/spring-beans.dtd'>
<beans>

  <bean id="avmNodeService" class="org.alfresco.repo.avm.AVMNodeService" init-method="init">
    <property name="dictionaryService" ref="dictionaryService" />
    <property name="avmService"        ref="avmLockingAwareService" />
    <property name="policyComponent"   ref="policyComponent" />
    <property name="invokePolicies"    value="true" />
  </bean>

</beans>

Thanks a lot, Peter.
Now everything works perfect!
I own you a beer!

I've also changed property classname to {http://www.alfresco.org/model/wcmmodel/1.0}avmcontent.
Here's the code:


<bean id="avmNodeService" class="org.alfresco.repo.avm.AVMNodeService" init-method="init">
    <property name="dictionaryService" ref="dictionaryService" />
    <property name="avmService"        ref="avmLockingAwareService" />
    <property name="policyComponent"   ref="policyComponent" />
    <property name="invokePolicies"    value="true" />
  </bean>

   <bean
   id="onUpdateAVMDoc" 
   class="org.alfresco.repo.policy.registration.ClassPolicyRegistration"
   parent="policyRegistration">
        <property name="policyName">
          <value>{http://www.alfresco.org}onContentUpdate</value>
              </property>
              <property name="className">
                  <value>{http://www.alfresco.org/model/wcmmodel/1.0}avmcontent</value>
              </property>
              <property name="behaviour">
                 <bean class="org.alfresco.repo.jscript.ScriptBehaviour" parent="scriptBehaviour">
                              <property name="location">
                                      <bean class="org.alfresco.repo.jscript.ClasspathScriptLocation">
                                      <constructor-arg>
                                         <value>alfresco/extension/scripts/onContentUpdate.js</value>
                  </constructor-arg>
                                     </bean>
                              </property>
                 </bean>
              </property>
    </bean>

it looks like this does no longer works:


    public ChildAssociationRef createNode(
            NodeRef parentRef,
            QName assocTypeQName,
            QName assocQName,
            QName nodeTypeQName,
            Map<QName, Serializable> properties)
            throws InvalidNodeRefException, InvalidTypeException
    {
        // AVM stores only allow simple child associations.
        if (!assocTypeQName.equals(ContentModel.ASSOC_CONTAINS))
        {
            throw new InvalidTypeException(assocTypeQName);
        }
        String nodeName = assocQName.getLocalName();
        Pair<Integer, String> avmVersionPath = AVMNodeConverter.ToAVMVersionPath(parentRef);
        int version = avmVersionPath.getFirst();
        if (version >= 0)
        {
            throw new InvalidNodeRefException("Read only store.", parentRef);
        }
        String avmPath = avmVersionPath.getSecond();
        // Invoke policy behavior.
        // invokeBeforeUpdateNode(parentRef);
        // invokeBeforeCreateNode(parentRef, assocTypeQName, assocQName, nodeTypeQName);
        // Look up the type definition in the dictionary.
        TypeDefinition nodeTypeDef = dictionaryService.getType(nodeTypeQName);
        // Do the creates for supported types, or error out.
        try
        {
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

the policy invokations are all commented out. Is there any good reason why I should NOT uncomment it? 🙂
