Thanks for the reply David.
Yeah, 'action' checking is another way of determining wether or not to
do the validation.
I guess I was wondering if it was possible to configure the Form to
prevent first time checking ? Would anyone else find this useful ?
Given the recent discussions about preventing direct acces to JSP's, it
seems that the Form validation is designed [in default operation] in
such a way as to expect that you have gone directly to the JSP first.
This is one thing I wouldnt really ever want to do, as I prefer all
requests to go through an action - even if it is just to redirect to the
JSP [call me a control freak! but there area lot of others that feel the
same :) ]
I wonder if the Auto Validation should accomodate the more common
scenario [certainly in larger applications] where you do want to force
requests thru actions and avoid direct JSP access, but avoid first time
validation. I guess Action Form could be extended to provide this, but I
was hoping it would already be there - as it seems quite obvious and
important. I dont think we should be encouraging people to go directly
to the JSP as part of the Struts framework [just my 2p]
Picking up on what you mentioned David, about handling all 'actions'
todo with a form in the one Action class. We have some sceanrios where
this is just not practical. What about those scenarios ?!
Thanks anyway David.
Any other comments ?
