Validator vs form Validate() method.
Hi folks,
I've gotten myself sorely confused here...
I've set up the validator to do simple validation on my forms. By "simple
validation" I mean checking for required fields and integer input, etc.
I need to use the validate() method to do more complex validation on one
form, I need to verify that a date the user enters is in the future.
The problem is that it seems that as soon as I implement the validate()
method in my form, it seems to bypass the validator, all those checks are
no longer done. If I comment out validate(), the validator starts working
again. (Note: This is the behavior I see whether or not the validation in
validate() passes or fails)
Have I got something configured incorrectly, or is this the way its
intended to work?
Thanx!
c'ya
Mike

Here is the solution I think....
In section 12.10.5 of Struts in Action by Ted Husted
There is an example of how to combine validator with the validate
method.
try this code
public ActionErrors validate(.....) {
ActionErrors errors = super.validate(mapping, request);
if(errors == null) errors = new ActionErrors();
....Continue with your custom validation...
}
Let me know if that works.

Ahh after a little research I think I might have answered that wrong.
What is your action form extending?

Are you remembering to call super.validate() somewhere in your
validate() method's implementation? You probably want to do that at the
beginning, so that it will perform all the "simple" validations that are
defined by your validator framework rules (which is embedded in the
validate() method of the standard form bean class); then, if no errors
have been encountered, you can hard code the more complex validations.

I am just a newB but couldn't you call the validate method from your
execute method. This way the validator will catch any of the easy
validations and your validate method will get the complex ones.
Again just a newB answer.
