behaviour not triggered on property changed

tcuser

Hi all,

I'm trying to bind an Alfresco behaviour to a certain custom aspect preoperty change, but it isn't never triggered.

My aspect is defined as follows:

 
      <aspect name="sc:customAspect">
         <title>Custom Aspect</title>
         <properties>
            <property name="sc:customProperty">
               <type>d:text</type>
            </property>
         </properties>
      </aspect>
‍‍‍‍‍‍‍‍‍‍

I want my behaviour to be triggered when customProperty is changed, so my init method is:

 
    public void init() {

        this.policyComponent.bindPropertyBehaviour(NodeServicePolicies.OnUpdatePropertiesPolicy.QNAME,
                QName.createQName(TcModel.NAMESPACE_TC_CONTENT_MODEL, TcModel.ASPECT_CUSTOM_ASPECT),
                QName.createQName(TcModel.NAMESPACE_TC_CONTENT_MODEL, TcModel.PROP_CUSTOM_PROPERTY),
                new JavaBehaviour(this, "onUpdateProperties", NotificationFrequency.TRANSACTION_COMMIT));

    }
‍‍‍‍‍‍‍‍‍‍

And the onUpdateProperties method is never reached. If I change my init mthod to:

 
    public void init() {

        this.policyComponent.bindClassBehaviour(NodeServicePolicies.OnUpdatePropertiesPolicy.QNAME,
                QName.createQName(TcModel.NAMESPACE_TC_CONTENT_MODEL, TcModel.ASPECT_CUSTOM_ASPECT),
                new JavaBehaviour(this, "onUpdateProperties", NotificationFrequency.TRANSACTION_COMMIT));

    }
‍‍‍‍‍‍‍‍‍

It works, but the problem is that it enters in onUpdateProperties everyTime I change any property of the node.

How can I bind the behaviour in this case? Thank you!!

Does your class implement NodeServicePolicies.OnUpdatePropertiesPolicy?

Yes, this is the full class code:

public class WFBehaviour implements NodeServicePolicies.OnUpdatePropertiesPolicy {

    private NodeService nodeService;
    private PolicyComponent policyComponent;

    public NodeService getNodeService() {
        return nodeService;
    }

    public void setNodeService(NodeService nodeService) {
        this.nodeService = nodeService;
    }

    public PolicyComponent getPolicyComponent() {
        return policyComponent;
    }

    public void setPolicyComponent(PolicyComponent policyComponent) {
        this.policyComponent = policyComponent;
    }

    public void init() {

        this.policyComponent.bindPropertyBehaviour(NodeServicePolicies.OnUpdatePropertiesPolicy.QNAME,
                QName.createQName("http://www.mycompany.com/model/content/1.0", "customAspect"),
                QName.createQName("http://www.mycompany.com/model/content/1.0", "customProperty"),
                new JavaBehaviour(this, "onUpdateProperties", NotificationFrequency.EVERY_EVENT));

    }

    @Override
    public void onUpdateProperties(NodeRef arg0, Map<QName, Serializable> arg1, Map<QName, Serializable> arg2) {

        System.out.println("onUpdateProperties IN");

    }

}

And this is the spring context:

   <bean id="wfPolicy" class="com.mycompany.alfresco.behavior.WFBehaviour" init-method="init">
      <property name="policyComponent" ref="policyComponent" />
      <property name="nodeService" ref="NodeService" />
   </bean>

Hi, I believe bindPropertyBehaviour is not getting triggered not sure if bug. You may try bindClassBehaviour.

         

this.policyComponent.bindClassBehaviour(NodeServicePolicies.OnUpdatePropertiesPolicy.QNAME,
                QName.createQName("http://www.mycompany.com/model/content/1.0", "customAspect"),
                new JavaBehaviour(this, "onUpdateProperties", NotificationFrequency.EVERY_EVENT));

Thank you, niketapatel. That's how I finally made it, but in that case I have to use an if inside the onUpdateProperties method to control that the property that has change is mu customProperty…

niketapatel

Yes true. Its bound to your customAspect. So if any property from your customAspect gets changed then only it gets triggered. So yes need to use if to check your specific custom property.
