Triggering an action on form display

[Aleksei Valikov <va...@gmx.net>]

Hi.

Could a anyone give me a quick hint?

I need a certain action to be triggered every time the form is displayed.

For instance, I have implemented some kind of validation for my business 
objects and depending on the validation results, I'll display different 
messages. (This validation has nothing to do with JSF validation of 
forms, this is something completely different.)
Doing this "on button click" is extremely easy - simply 
action="#{myContainer.validate}" and that's it.

Now I'd like to implement "instant validation", that is, that my 
validate() method is triggered automatically after model values are 
updated. Probably somewhere before form rendering phase. My question is, 
how can I receive a notification of the appropriate event in my bean?

Thank you for you time.

Bye.
