Setting focus on field with error

["Molitor, Stephen" <SM...@erac.com>]

Is their a nifty way to have the focus automagically go to the field with
the error, on an input form?  For example, if I have a form with an 'amount'
field, and the user enters an invalid amount, causing my Action to return an
appropriate error, keyed in the ActionErrors container with the 'amount'
property, is there a slick way to have the focus set to that field on the
form?  I know how to have the error message display next to the offending
field, but having the focus go there also would be nice.

Thanks!

oops, wasn't thinking straight. The validate method takes the request as an 
argument so you wouldn't need to forgo automatic form validation.

I could be wrong but I can't think of anything that would be very convenient. 
The only way I could imagine doing it (and I'm not sure it would even work) 
would be to invoke a javascript function every time the page loads. You could 
add a bean with the data needed by the javascript  to the request, from your 
action class. NOTE: this would require you to forgo the automatic form 
validation and instead trigger validation from your action class. This is the 
only way to get the bean I talked about into the request (as a request 
attribute that is).
