[TYPO3-mvc] The value must be of type "Extension_model_name", but was of type "NULL".

[Alisha]

Hi,
i renamed my models, but the error is the same..
The value must be of type "Tx_Dancestudio_Domain_Model_Couple", but was 
of type "NULL".

Property 'couple' could not be set. (#1236783102)

What is the problem? i don't understand it...
