Alfresco form filters

I'm trying to create a form filter, that would do some post-processing of a form.

What I'm trying to achieve: Everytime a node has been created OR modified the filter should be applied after the node is persisted.

It runs just fine when i edit/modify an existing, but it does not run after a new node is created.

Here is my code:

    public class CaseFormFilter extends AbstractFilter<Object, NodeRef>
{
    protected ServiceRegistry registry; 
    protected NodeService nodeService;
    protected SearchService searchService;
    protected SiteService siteService;
    protected NamespaceService namespaceService;

    public void setServiceRegistry (ServiceRegistry registry) 
    { 
        this.registry      = registry;
        this.nodeService   = this.registry.getNodeService();
        this.searchService = this.registry.getSearchService();
        this.siteService   = this.registry.getSiteService();
        this.namespaceService = this.registry.getNamespaceService();

    }

    @Override public void afterPersist(Object item, FormData data, NodeRef persistedObject)
    {
    System.out.println("Persisting!");

    }

    @Override public void afterGenerate(Object item, List fields, List forcedFields, Form form, Map context) 
    {
        System.out.println("Calling afterGenerate!!");
    }

    @Override public void beforeGenerate(Object item, List fields,
                      List forcedFields, Form form, Map context) 
    {
        System.out.println("Calling beforeGenerate!!");
    }

    @Override public void beforePersist(Object item, FormData data) 
    {
        System.out.println("Calling beforePersist!!");

    }

}

I can see that beforeGenerate and afterGenerate is always called, even when viewing, which makes sense. However, afterPersist is only run when I edit a node, but not when creating a new node.

Am I doing something wrong or missing something? The wiki/documentation is rather useless on this point, reading http://wiki.alfresco.com/wiki/Forms_Developer_Guide#Form_Filter just tells me to look in the DOD5015 module, which does provide an example, but does not really provide any answers.

I'm using Alfresco 4.0.b Community edition.

EDIT: A bit more clarification

You have to register your form filter twice. I'm guessing you currently only register it with the nodeFilterRegistry. For a form based on the content model (creating a node) you need to register your filter with the typeFilterRegistry.

Here is an example for a form filter configuration with both registries:

<bean id="yourFormFilterNode" class="com.domain.YourFormFilter" parent="baseFormFilter">
    <property name="filterRegistry" ref="nodeFilterRegistry" />
    <property name="nodeService" ref="nodeService" />
</bean>

<bean id="yourFormFilterType" class="com.domain.YourFormFilter" parent="baseFormFilter">
    <property name="filterRegistry" ref="typeFilterRegistry" />
    <property name="nodeService" ref="nodeService" />
</bean>

It's rather obvious that afterPersist is only called when submitted, because on viewing you're not 'persisting' any data.

So in most case you'll only need before/afterGenerate.
