[TYPO3-core] RFC #16336: Bug: tcaTree does only support irre foreign_field relation on "parentField"

[Steffen Ritter]

Hey list,
This is an SVN patch request.

Type: Bug

Bugtracker references:
http://bugs.typo3.org/view.php?id=16336

Branches:
trunk

Problem:
tcaTree does only support irre foreign_field relation on "parentField"

Solution:
implement it

Notes:
parentField using mm does only work if you gave a rootUid (because 
t3lib_loadDBGroup  is not able to "deliver all records which do not have 
any mm relation - which would be the definition of "root records" which 
have parents via mm)



regards
Steffen
