Thomas, 
I am unable to reproduce the issues you are having with the View/Edit mode and filter drop down.  I have installed a clean copy of DNN 6.0.2, and installed the Repository module 3.5.5 Beta (with the updated .dll)

I am able to switch back and forth from View to Edit and back, I setup categories and am able to filter the list using both the category dropdown in the header, and a dashboard module I placed on the same page. 

It all works as expected with no errors on the screen or in the event log.

 Hi Steve,
thank you for digging into it. My installation is obviously not a clean 6.0.2 one, but an upgrade of an upgrade of an upgrade startin from somewhat 4.3 when I remember correctly. So it might be an issue with that. I have to install a clean one beside and try to switch over. Dunno how to do that in detail, but that is not a problem of this thread.

Interestingly also a direct jump to an item does not work e.g. when coming from the search results of the site. It jumps to the main repository page, but not into the item that was found. But I do not see any errors in the log. When I switch myself into edit mode (e.g. as admin) and then do the search and the jump it works. This is quite strange. Could it come from the "personal repository" feature or the "item level security" feature ? Do I have to cleanup/default some columns in the upgraded database to fix that ?

However, I will further try
Thanks for your effort

Regards
Thomas


P.S.
I have already solved my text editing problem that comes from the FCKEditor. Switched to the Dotnetnuke.RADEditor provider and all is fine. No need to worry about that.... pfuh.
