I was wondering if anyone can help track down this error that I'm
getting. Unfortunately, I cannot reproduce the error with any
consistency - just sort of appears to happen randomly. My debug log &
stack trace is below. It happens only when a user submits this one
form that may (or may not) contain a file - along with other
information. I get the error in the "validateUpdate()" function of
the action and it appears that the "model" of the action
(xactionActivity) is null. How can the model "sometimes" be null if
it's set via the form? I have included my action setup thinking it
may have something to do with my interceptors? The user never sees
the error on the webpage, it just shows up in the logs. I'm really at
a loss for this one. Let me know if I need to share more information
to help. Any ideas are appreciated....
