How to create my own ObjectCreateFormProcessor

Hi to all!

I need to get the oid after persistable object creation. I have created my own FormProcessor that extends CreateObjectFormProcessor.

I have overrided create action for the promotion request object like follow:

<action name="create" selectRequired="true" ajax="component" uicomponent="PROMOTE">

       <description>Promote create wizard</description>

        <command class="ext.myComp.formProcessor.CreatePRFormProcessor" method="myMethod" windowType="popup"/>

         <includeFilter name="restrictGuestMembers"/>

      </action>

But my own method didn't called after user finish the wizard. As I know system call the execute(NmCommandBean) method. So how can I call my own method? Thanks
