form validation with parameters

[leela]

Hi,

 Is it possible to trigger only a particular validation rule defined on a validatebox?
 I would defined a custom Validate Rule on some elements of the form.
 I need to trigger different validation rules for different button clicks.
 Right now when you say form.form('validate'), it validates all the validation rules defined on all the form elements.
 I need something like form.form('validate' sourceButton)
 and make this sourceButton available in my Custom Validation Rule function, based on the source button clicked I would decide if i should run that validation or not.
 Is there a way to achieve this?

Thanks,
Leela.
