bindAssociationBehaviour ... how?

marcus — Mon, 16 Oct 2006 06:20:23 GMT

I'm trying to bind a behaviour to the onCreateChildAssociation event, but can't figure out what's meant for what… as you can see below, I've tried binding against both the parent and child class of the association, but my method for implementing the behaviour is never getting called when I add a new

Hi,

I think that the problem is your parameters:

this.policyComponent.bindAssociationBehaviour(
         onCreateChildName,
         ContentModel.TYPE_FOLDER,
         new JavaBehaviour(this, "onCreateChildAssociation")
   );

You should replace the 'ContentModel.TYPE_FOLDER' argument by the 'this' reserved keyword, but in this case, each children associations will trigger this behavior…

Take a glance at the following Alfresco's code, it may help you to understand : org.alfresco.repo.node.index.NodeIndexer

I think you can also specify on which association the behavior should be triggered through an overloaded version of the function.
In this one ,you can specify the associationRef QName.

See org.alfresco.repo.policy.PolicyComponent interface :

/**
* Bind an Association specific behaviour to an Association-level Policy
*
* @param policy the policy name
* @param className the class to bind against
* @param assocRef the association to bind against
* @param behaviour the behaviour
* @return the registered behaviour definition
*/
public BehaviourDefinition<ClassFeatureBehaviourBinding> bindAssociationBehaviour(QName policy, QName className, QName assocName, Behaviour behaviour);

Hope it helps,

JMarc

Thanks for the reply. I had seen the NodeIndexer code actually, but it's not quite what I'm after as that uses service level association behaviour, which from what I can tell is executed for every association. The one I'm trying to use is for specific types of classes involved in the associations (like what you posted, but without the assocQName). Thanks anyway
