By the way many thanks for the exceptional work on the standard tag library. It's really a joy to work with. As an experiment, I'm porting some scriptlet-laden pages to JSTL. It's amazing how much it cleans things up.
The one thing I really would have liked was the ability to test the size of a collection before I iterate it. (in my case I needed to know when there is exactly 1 item) I know there was a discussion on this a little while ago and saw your workaround to pre-iterate it, but it's not a practical solution for large collections. So while I had your ear, I just wanted get my vote in to add some way to do it. Although I'm sure it's too late. --LH -----Original Message----- From: Shawn Bayern [mailto:[EMAIL PROTECTED]] Sent: Wednesday, April 24, 2002 4:20 PM To: Tag Libraries Users List Subject: Re: [standard] query tag exception when no session (By the way -- many thanks for reporting the issue!
