Change css-class of form on validation
Hi@all,
I want to use a different css-class for my inputfields after the validation
of that field has failed. For example, if an requiredfield isn't filled, the
field should get red.
Does anybody knows how to do this? Furthermore I do not want to have the
message "field ... is required" in my feedback panel.
Thanks
Sebastian

this.component = component;

Or something like that.
It's a bit tricky if you want to make it work on ajax (e.g.
with OnChangeAjaxBehavior, I think you have to explicitly
call validate() or something), but very cool :)
Best wishes,
Timo

Well, why do you think? You're calling getClassValue() once, at
constructor time.
Take a look at the other constructors for AttributeModifier.

Hmmm... - sorry, but one more question on this. I added an attributemodifier
to my component. When accessing the page the attribute is correctly
renderred. But I want to "rerender" the component after the validation
failed. But the validation method isn't called again.
example: myfield.add(new AttributeModifier("class", getClassValue());
The method getClassValue is only called when the page is displayed the first
time. After validation I want to called it again, but it isn't. Does anybody
knows why???
Thanks,
Sebastian

But in which message do I have to override it?
I use the RequiredText- and PasswordTextField. Do I have to extend this
classes with my own versions or where I can override the message?

Then override the message with an empty string.
Add an attribute modifier that modifies the class attribute when the
form component is invalid.
