[TYPO3-mvc] creating/deleting mm-realations between existing entities in front end? - SOLVED

[Uwe Michelfelder]

Hi,

I answer this thread to myself, so that if someone stumbles over this,
with the same problem, can read the solution here, too! ;-)

Solution was:

1. correct TCA-Configuration concerning the MM-Relatino table, etc. and
exttables.php

2. IN GENERAL: never use exit(); for debugging and let run extbase till
it finishes...... I think this will prevent a lot of headaches for me in
the future....

Greets,
Uwe
