[TYPO3-mvc] How to validate if input value is unique in table?

[Uwe Michelfelder]

Hello Manuel,

thankks sharing your knowledge on this. I tried to do this on directly
in the Domain Model. Now I do it on the Controler Action, just like you
suggestet, and it works.

But one more question. How do you fill the error-Stack for the proporty
which I just validated, so the formfield shows the error class?

Greetings,
Uwe
