[TYPO3-mvc] error in TCA: (travel) Probably value mismatch with fieldtype.

[Domi]

Hey Hanjo,

thanks for your reply. In my DomainModel I have a n:1 relation from 
Travel.city -> City.uid and bedirect 1:n relation from City.travel 
->Travel.uid. Both table columns, Travel.city and City.travel are int 
because they only should show ID / Count of relations.

Isn't that right? Or how can I make a n:1 relation editable from both 
sides through the backend list view?

Cheers
Dominic
