Log into the jBPM5 console. After you refresh your browser window (by pressing F5, for example), you are logged out. This is not how any other web application behaves and definitely not the expected behavior.
Porcelli is looking into this one, he doesn't have BZ rights yet, so can't assign it to him.
After a discussion with Porcelli, the bpm-console uses errai-workspaces (unfortunately workspaces aren't supported anymore) and this issue is completely related to errai workspaces. Solving this would require a substantial effort (approx. 1 week). Since we're moving away from errai workspaces for the next version, we believe it might be best to address this issue in a future release.
