Hi,
I think I have a similar problem, at least the stack trace looks like
mine. At me this only happens if Stripes' SourcepageResolution points to
a JSP with nested stripes layouts. My (ugly) fix: I put the validation
logic into the handler method. If I want to trigger a validation error,
I explicit return a forward to the concrete target JSP (works fine), not
the sourgePageResolution (throws NPE like CN Yee's one).
Greetings,
Marcus
