Defer call to preDecorateScript() till onSubmit() is called?

[Julian Sinai <js...@yahoo.com>]

Hi, I need to display a confirmation message to the user before submitting a form. It's pretty standard to use the code below when the message is known at the time of button or link construction. But what about when the message must be synthesized at the time of the button click? I've tried using a model, but that didn't help. I would appreciate any help.

Thanks,
Julian


@Override
protected IAjaxCallDecorator getAjaxCallDecorator()
{
return new AjaxPreprocessingCallDecorator(super.getAjaxCallDecorator())
{
@Override
public CharSequence preDecorateScript(CharSequence script)
{
 return "if(!confirm('" + message
      + "')) return false;" + script; 
}
};
}

You'd probably need to return script that can create the message
client-side, for instance, if you're creating the message based on fields in
the form.  I'm not sure if you need to generate the message server-side.
