We have set up a new installation of LiveCycle ES with weblogic. Everything seems to be working fine but we can't check-in or check out files.
Actually, a new file can be created and checked-in to the repository only once. Further modifications of the files can't be checked in (the option in the right-click menu is grayed), and the little arrow on the icon does not appear after a check out.
There is no error message (nor popup, nor specific line in the logs)
Same problem on different computers so it seems to be a problem on the server side.
