Ah, I meant to try to answer this, but it slipped through... I wasn't sure exactly what you meant by "change the scope on one of the attributes on our tags." You can use <c:set> to override an existing attribute, and thus to change the scope of a scoped variable:
<c:set var="foo" scope="session" value="${page.foo}"/> but I'm not sure if that's what you mean. You can't make the 'scope' attribute dynamic, which might be another thing you mean. That is, you can't say scope="${myscope}". This restriction is designed primarily to aid tool support and translation-time error checking. If you need to decide on the fly what scope to use, you'll need to use a <c:if> or <c:choose> block. We didn't consider this case very common, so the somewhat circuitous solution didn't seem to be a major issue. (Hmm, that's the first I've used the word "circuitous" to actually refer to circuit-like logic. I wonder if that counts as a pun or not...) -- Shawn Bayern Author, "JSP Standard Tag Library" http://www.jstlbook.com (coming this spring from Manning Publications) On Mon, 11 Mar 2002, Steve Bang wrote: > Can anyone help me on this? > > Thanks, > Steve > > > -----Original Message----- > > From: Steve Bang [mailto:[EMAIL PROTECTED]] > > Sent: Friday, March 08, 2002 11:03 AM > > To: 'Tag Libraries Users List' > > Subject: Using <set> to change scope > > > > > > We have a custom tag library that treats all of our tags with > > a session scope (by design).
