You're gonna love this one :-). In the very early days of Struts, different implementations of JSP (and particularly TagSupport) were buggy around how they dealt with the "id" attribute -- partially because the early specs were more than a little fuzzy on the required behavior. To guarantee consistent behavior, we had to use some other attribute instead, and chose to use "styleId" as a complement to "styleClass". Now, of course, the implementations are much more consistent -- but backwards compatibility breakage would occur if we tried to change the behavior of the tags. Regards, > Brian. Craig
