Subject: Re: Help - I cannot validate a simple form with 2 fields
I really dont get it, I might be being so stupid not figuring out what
is going on wrong here, but I dont.
Clearing a little. I decided not to use DynaForm and go back to the
usual ActionForm and gave up using Client-side validation.
When I implement the validate method of the Bean (as it is now) I get
the error messages as expected, but I had to create a protected method
to check if the field was null or blank, then put the error message in
the ActionMessage.
But I dont see any sense in doing such thing like that, why should I do
this inside validate method if I have already said in validation.xml
that those fields are REQUIRED, at least that message should be shown to
the user. Correct me if I am wrong.
If I comment the validate method nothing happen, it is not able to check
if the field was left blank.
Please be pacience and have a look again:
