I have deleted the folders on the mid-tier server, and deleted temporary internet files in Internet explorer (by going to Tools -> Internet Options), and then closing all browser windows... Clearing the local cache doesn't fix it (the messed up fields). Sometimes, that does fix the "Caught Exception" errors though, but not always. If we clear the server cache, it will usually resolve the issue for that user, but then other users have issues. So, basically, we spend all day clearing the mid-tier cache.

In our 7.6.04 SP2 installation, we've found that if we flush only the mid-tier cache without also having the users clear their browser caches (and they need to FULLY clear their browser caches by closing ALL open browser windows, marking every possible option for clearing in IE - our site-standard browser, then going in and deleting any leftover files - I can send you the full procedure if you use IE at your site), then behavior similar to what you describe happens. We've particularly seen behavior like this when we upgraded the ITSM application itself, but I would recommend doing it even for a mid-tier-only upgrade. It's like both the server side and user side caches need to be fully refreshed in order for everything to work right. And if you do this and still have issues, you can be confident that the problem isn't being obscured or caused by caching conflicts. We've found that in going to ITSM, we've had to become very familiar with the web browser - how its settings affect behavior in ITSM and how to clear its cache properly so that you get a "clean" pull from ITSM. Good luck!

We just upgraded from 7.5 and are having issues since the upgrade. What we are seeing are certain fields duplicated and in strange places. We are also getting "Caught exception" errors (there are several different errors, but they all start with Caught exception). We are in a load balanced environment. When a user is having an issue, if they go to the other server, they are usually fine (but sometimes, it's messed up, but it's a different field duplicated and in the wrong place). Usually, if we clear the cache on the server, that will clear up the issue, but then another user will have a different field that's messed up. I've read back through the list and seen others with similar issues, and followed the suggestions, but they haven't fixed the issue. Here is what I have tried so far: 1. Delete bak files 2. Deleted cache directories 3. Added the results list on all views (on the forms where we have seen the issue) 4. Increased the java heap size 5. Turned off the persistence cache in the mid tier console I have looked at some of the hot fixes, but they don't seem to have any fixes for our issues. Here's our full mid-tier version: 7.6.04 SP3 201201302357. We are on Windows 2008, 64GB ram. We have a ticket open with BMC, but they just keep asking us for logs.
