RELM: Error when saving a view - CRCPD1021E

This typically happens when you try to save a stale form (you attempt to save after another user has modified the view, so there's a conflict). However, the information provided is insufficient to reproduce the problem.

Here are some questions we'd like answered:
Does the error happen consistently (can you reproduce it on demand)?
Does it happen on all views?
Are there other users using the system when this happens?
If you reload the view and then save, does it work?
Can you request relm.log and jts.log?
Can you reproduce this anywhere else?
What is the system topology: WAS or Tomcat, use reverse proxy, host name and public URI, etc.?
What version of RELM is this?

Error CRCPD1021E can easily be reproduced if you try to save the same view from different tabs. So, first check that the view having the issue is not opened in another tab. If the issue persists and doesn't even go away after reloading the page, you may be using IE9. Try other browsers (e.g. IE10/11, FireFox or Chrome), do you still see the problem? It is know that under some circumstances IE9 is unable to correctly process etags information embedded in the response header whereas it can be understood by most of recent browsers.
