Yes, my qualm is with the 'jsp' prefix. My problem is that (even though it would be good if we didn't) we have many automated tests that have been written using the old ids (and they are the same ids as the RI, so the same tests work with the RI as well).
I know the 'right' long-term solution is to make our tests id-independent (or assign ids to everything in out JSP file). Given that this isn't a JSF 1.2 implementation, I was hoping for a short term fix to my problem, but it sounds like your current solution depends on the prefix being different from the Servlet id prefix. > -----Original Message----- > From: Jacob Hookom [mailto:[EMAIL PROTECTED] > Sent: Wednesday, July 12, 2006 11:51 PM > To: MyFaces Development > Subject: Re: Ids in 1.1.3 and 1.1.4 > > Unique Id generation aside, I think the qualm was with the 'jsp' prefix > in the generated IDs.
