Dear Jeremy .. what do you mean with "should I "hide" fields rather than "not display" fields.. ??", "hide" and "not display" are the same things isn't it :-)
if you're expect the validwhen to manage hide and unhide HTML object, validwhen couldn't do such a thing. ===== Taken from struts doc : [Since Struts 1.2.0] A frequent requirement in validation design is to validate one field against another (for example, if you have asked the user to type in a password twice for confirmation, to make sure that the values match.) In addition, there are fields in a form that may only be required if other fields have certain values. The validwhen validation rule is designed to handle these cases. ===== Otherwise, to manage hide and unhide HTML Object which is generated by Struts, you can create your own javascript function to hide/unhide the object, and then call the function manually using OnChange property in your select tag.

I think now it's time to explain you clearly what I'm trying to do. I've got a select tag wich determine if some fieds appear or not. "if select value > 1, some input:text tags appears, and there aren't present is select value=1." Maybe should I "hide" fields rather than "not display" fields.. ?? thx On 7/25/06, Adam Gordon <[EMAIL PROTECTED]> wrote: > > Jeremy- > > Ok, sanity-check time.
