[TYPO3-mvc] Problem with saving a mm relation (frontend)

[Kerstin Eitner]

Hi everybody,

I solved the problem myself.
The important thing is to define the categories in the new-Template as a 
multiple field like:

<select id="category" style="width: 15em;" multiple="multiple" size="3" 
name="tx_my_list[newEvent][category][]"><option value="1">Konzert</option>

Then everything works fine!
Best regard
