Hi Carlin,
thanks a lot for the tip about the validator interface, this is
exactly what I was looking for.
Not a new problem arised, maybe hopefully you can help me out with
this as well. I am using page flow controller inheritance.
public class ParentController extends ... {
@Jpf.Action( ... validationErrorForward = Jpf.NavigateTo.currentPage )
public Forward submit(FormBean form) { ... }
}
The child flow controller has inheritLocalPaths set to true and does
not overwrite the action method.
When I submit the form bean, which has been enhanced with the
Validator interface, and the validation fails, I would expect the user
to be forwarded back to the input page. However, I receive an
exception:
org.apache.beehive.netui.pageflow.NoPreviousPageException: No relevant
page for return-to="currentPage"
If I use a path in the validationErrorForward instead of NavigateTo,
no exception occurs but no JSP is being rendered. =(
Do you have any ideas?
Thanks a lot,
<P>
