Subject Re: modifying the mapping input path during validation
Date Tue, 17 Dec 2002 20:58:23 GMT
I'm getting more than I bargained for here with the whole tiles aspect, 
so I might be done helping now that the complexity has gone up, but just 
a bit more here....

You need name="..." for this action mapping.  That should solve the 
issue, it seems.

Yes, but only if you tell your action mapping the form bean associated 
with it, and from what you showed above, you don't.

It was a joke.  I dig action chaining.  Others do not.  See previous 
thread a few days ago.

Or keeping the form bean around and using it.  And I agree with the 
session scope page flow comment - its not necessary in my experience.
