focus in a select multiple on custom validation class

Hi,
I'm here again with a problem in my custom validation class, after hard work I get success in making a custom validation class to my form, one thing I can't fix, when an error occur, the select multiple input does't get focus.I tried in a text input field and it focus on an error, only the select multiple field didn't work out.
Do you have any idea what it might be?

best regards and thanks one more time.

Wilson

It is hard to tell. Does it happen in all browsers? Can you provide a minimal example script so I can try to reproduce the problem?

bingo, in firefox works fine, the problem appears only in IE.
My form is very big and today I can't make a small functional version, but bellow there is more pieces related to the problem.

thanks,
Wilson

The JavaScript code to give the focus to the invalid input is the same to all browsers. If it does not look like it got the focus, maybe the browser is not showing the presentation of the input in a way that you see clearly.

Maybe it is a matter of using a CSS style definition for the invalid style that the browser actually uses and make the input look differently. Try setting some border color and style properties in the invalid style.

Thank you, as usual your tips are magic, I change the InvalidSTYLE attributes and the IE accepted. I guess that the problema is with the border-color that never change, but it's not a problem, I'm using another way to focus, like background-color.

The flexibility of forms Generation is impressing.
