[TYPO3-mvc] fluid selector - Argument passed to x must be an instance of y, string given

[Claus Due]

Hi Christian,

uid is the default key. This sounds more like a problem with the property mapper. Could you check which value is being POST'ed to the controller? I suspect it could be an empty which causes this problem - in which case you should be able to get around it by allowing a default value of NULL in your setter: setAsbildungsschwerpunkt($punkt=NULL).

Hope this helps.

Claus

I compared my code with the blog_example (where a list of administrators is loaded into a selector) but I can't figure out the difference. Everything from the controller, tot he form and model is done the same way...
