How can i avoid this validation error in a create action?
Everything worked so far, but since one of the last updates i get this....

i create an object with a relation to an other entity and not mather if i do
<f:form.hidden property="package" value="{request.package}" />

or
<f:form.hidden property="package" value="{request.package.uid}" />

it just throws me that validation error.

when printing the mappingconfiguration in an initializeAction everything seems fine, all properties listed below propertiesToBeMapped
