Subject RE: [S2] Action chaining and validation problem
Date Wed, 17 Sep 2008 18:21:33 GMT

check  your validators.xml to see if your short-circuit attribute is set to true
The invokemethod grants the Interceptor the power to short-circuiting the Action Invocation.

Instead of calling invoke, the Interceptor can 
return a result String and 
bypass any remaining Interceptors on the stack and the Action's execute method.
   <!-- Field Validators for email field -->
   <field name="email">
       <field-validator type="required" short-circuit="true">
you'll want to set short-circuit="false" to allow interceptors and execute to be invoked
