[TYPO3-mvc] Complex array validation

It wasn't - so I've added the above lines to the controller action.
But... now I get a new exception from the cache handler - and before I 
do some serious debugging, I'd like to hear if you have any simple 
suggestions.

#1233058486: "" is not a valid cache entry identifier

The stacktrace looks a bit like this:

67 t3lib_cache_frontend_AbstractFrontend::has("")
66 Tx_Extbase_Object_Container_ClassInfoCache::has("")
65 Tx_Extbase_Object_Container_Container::getClassInfo("")
64 Tx_Extbase_Object_Container_Container::getInstanceInternal("", array)
63 Tx_Extbase_Object_Container_Container::getInstance("", array)
62 Tx_Extbase_Object_ObjectManager::get("")
61 Tx_Fed_ViewHelpers_Form_GroupViewHelper::render()

It seems that the GroupViewHelper tries to instantiate an empty class 
name, so could it be because of some kind of missing annotation 
(although I've created my models through the extension builder - so it 
should be in order).

My fluid template now looks like this:

<f:form class="clearfix" method="post" action="create" 
enctype="multipart/form-data"  name="newInquiry" object="{newInquiry}">
   ...
   <fed:form.group amount="1" property="{newInquiry.oensker}" 
iteration="iteration">
     <f:form.textfield property="{property.fraDato.name}" 
class="calendar" />
     <f:form.textfield property="{property.tilDato.name}" 
class="calendar" />
   </fed:form.group>
   ...
</f:form>

Where newInquiry.oensker is the objectStorage property and fraDato and 
tilDato are properties on the sub model.
