Yes, this was originally what I was looking for. -----Original Message----- From: Paulsen, Jay [mailto:[EMAIL PROTECTED] Sent: Wednesday, April 02, 2003 11:13 AM To: [EMAIL PROTECTED] Subject: RE: [displaytag-user] easy way to sort simple String columns case-insensitively?
I'm not sure there's a way to do it generically. It would be nice to be able to do this in a jsp: <display:table name="foo"> <display:column property="bar" sort="true" caseInsensitiveSort="true"/> </display:table> and have the table tag automagically take care of it.
