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

[Christian Essl]

Hi,

I now added optionValueField:

      <f:form.select id="ausbildungsschwerpunkt" property="ausbildungsschwerpunkt"
        options="{ausbildungsschwerpunkte}" optionLabelField="titel" optionValueField="uid">
      </f:form.select>

But the problem is still the same. Shouldn't uid be the default key?

Hi Christian,

Would you be able to use {object.uid} as the value argument of the selector? That should prevent your object vs. string error message.

Kind regards,
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...
