[TYPO3-dev] Bidirectional MM relations

[Tomi Hrovatin]

Hi and thanx again,

well, I saw that doc. I also looked in DAM but couldn't get it to work 
:(. I just can't dig what all these settings mean. DAM is also using 
settings for mmforeign extension. Yesterday I tested DAM without 
mmforeign and it works without the problem.

Can you explain on example from MM_oposite_field description or maybe 
have another working example?

I hope I don't ask too much.
