I suspect that there's something wrong with the implementation of JSF 1.2 used by JBoss, probably in that implementation's UIComponentClassicTagBase code or something similar. The behavior you're describing doesn't occur with Glassfish.

Hello, I have a project that is running Trinidad and I recently upgraded to JBoss 4.2.0.GA. As part of this upgrade I also migrated to JSF 1.2 (the latest Seam version requires me to do this). Ever since then, whenever I submit a form that fails validation, the form renders the correct validation messages but I get some weird rendering of the form. It's actually like the previous HTML doesn't get cleared and the new form + validation errors gets tacked onto the end - I'm literally seeing double. If I click my submit button again, then a third instance will be tacked onto the bottom, and so on. If at this point I simply refresh the page, then everything resets back to normal. If I use the application without causing validation errors then everything works as normal. I get the same behaviour on FireFox and IE and there are no exceptions in the logs. I tried updating the Trinidad build to trinidad-*-1.2-07-may-SNAPSHOT.jar, but to no avail. I eventually tracked the strange behaviour down to my usage of <trh:body>, if I use a vanilla body tag then the page duplication problem goes. However, I still get similar issues with <tr:commandLink> - the instance of the link is duplicated with each form submission that causes a validation error. Changing to <h:commandLink> again, resolves this issue. Has anyone come across this before? Cheers, Chris.
