Actions on client side validation errors

[burberius]

Hi

I started a new project (also my first steps) with RichFaces 4.1. The first part is just a simple login/portal site, with a nice usability created by a designer. While doing the styling I stumbled over two problems, where I couldn't find help in the book nor on the internet.

Is it possible to work with actions if a client side validation error occures?

My design girl wants two things based on an error:

• highlight the input field where the error occures and remove the highlighting when the field is OK again
• disable the submit button and enable again, when everything is fine

The first would be just some styling change when there is a validation error. The other would have to disable the button with javascript, I guess.

Any help would be a appreciated.

Best regards,

you can add different styleclasses based on some flag like an el expression

styleclass="#{M.b.flag?'normalStyle':'errorStyle'}"

same you can use for disabling the button

disabled="#{M.B.flag}"

u can use validators/ required attribute  for some basic validations.

But your suggestion only works with server side validation, when the form is rerendered.

Is there some place where I can find those flags? I only found component.valid which only works for the input field.
