Delete of items in trash is aborted if user logs off

[Jari Häkkinen]

As administrator I impersonate another user account and want to delete raw bioassays in the trash. I mark the raw bioassay I want to remove from trash and click 'Delete permanently', click on the 'Close' button in the popup, and logoff. The logoff popup is blocked for about 10 minutes before the logoff concludes successfully. However, the item that was to be removed did not go away.

Removing the item once more without logging out will within 1 minute remove the raw bioassay from the database.

The trashcan now uses a cloned session control and should not be affected if something happens (such as logout) with the original session control.
