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

[Henjo Hoeksma]

Hi Alisha,

a domain model should be preferably in the singular form, i.e.
'Domain_Model_Couple' instead of '...Model_Couples'.

I'm not sure but I guess this could trigger Extbase to handle it
inappropriately.

Couples is a plural description. Try kickstart a test extension with the
same model name in singular form.

Success!
