[TYPO3-core] RFC: #15290: Bug: Wrong behaviour of workspace preview setting "Enable Frontend Preview"

[Andreas Kiessling]

This is an SVN patch request.

Type: Bugfix

Bugtracker references:
http://bugs.typo3.org/view.php?id=15290

Branches: TYPO3_4-4, trunk

Problem:
Until 4.4 (see Bug 14097 / rev. 7359) the setting "Enable Frontend 
Preview" triggered this behavior:
unchecked = split-view with 3 frames to view live, draft and workspace 
management
checked = only selected workspace is shown in frontend

Current situation:
unchecked = preview shows live version of page, even when in a workspace
checked = split-view like mentioned above

Solution: the two generated urls for the preview modes need to be 
switched to restore the previous behaviour. Additionally, it needs to be 
checked if the live workspace is active, so the setting for "Enable 
Frontend Preview" can be discarded in this case.

Patches for 4.4 and trunk differ, because ext "version" was recently moved.


Regards,
Andreas
