[TYPO3-mvc] Relation-Field of existing objects not updated

[Joerg Schoppet]

Hi,

success-message was to early :-(

I'm totally stuck.

If I do it the way mentioned below, the positions are correctly updated 
with the invoice, but not the other way round. e.g. the imports-fields 
is not updated with "3", if I add the invoice to three importPositions.

If I manually update the invoice-record with "3" for imports I receive 
an internal server-error, when trying to fetch it within my 
extbase-extensions (perhaps a circle reference).

Can somebody give me a hint of how I can solve this problem?

My use-case is:
- Positions are created first
- Afterwards I want to select, which positions should be grouped 
"within" an invoice
- I must know, if a position is already assigned to an invoice
