I am creating easy CRUD application.
I am trying to use method validate in class extended ActionForm. But I am doing it wrong probably.

IF the line is uncommented:

1. If I remove the comment(above) in the validate method it will not call methods in class extended DispatchAction.
(These methods are call with commeted line and it work fine.)

2. Next issue: It will entry to the condition, if it entry to the form.
(getName() is null).

Could you help me, please.

hey manu,
I couldnt follow you completly. Why are you throwing that errror? Is it like name is required? and also if the user does not enter anything in the field the "getName()" will give you an empty string and not a null(as far as i know). So i think something like this may work:

So this will give an error everytime the user enters nothing,
I promise I will be the best, most loyal friend ever! All for this tiny ad:
