[TYPO3-mvc] Additional fields in mm-table

[Moritz Bützer]

Hi List

I've got two tables in relation with an mm table. In the mm table i need
additional fields. If i adding now a new relation with the attach() method,
all the existing relations getting overidden. It looks like extbase creates
for every relation a new entry and dont just adds one.

Does anynone knews a better way to maintain an mm table with additional
fields or is this not possible?

Thanks and kind regards
Moritz
