[TYPO3-core] RFC #16065: Bugfix - New layout and labels for tt_content show palette labels without content

[JoH asenau]

This is a SVN patch request.

Type: Bugfix

http://bugs.typo3.org/view.php?id=160365

Branches: trunk

Problem:
After 0016031 palette labels are displayed, although there is no option in the palette.
So you see a palette "headline", but no option below. This does not make sense; remove the palette label in that case!

Solution:
I tracked it down to the palette "item" --linebreak--
If there is a --linebreak-- left after removing excluded fields, the palette still gets rendered, since count($parts) will still be true.
Attached patch solves this problem by checking if $parts contains only --linebreak-- item(s) and removing the palette completely as well for this case.

Cheers

Joey
