[TYPO3-mvc] Relations to non existing Domain-Models (eg. fe_groups and sys_language)

[Christopher Hlubek]

Hi,

I think this patch is more or less right, but in the wrong place. A TCA
config without foreign class name shouldn't be considered a relation.
See the patch in my last message, where I fixed this issue to make our
app work (in the DataMap). Otherwise Extbase would be a little to greedy
for fields that should be a relation in the TCA for the backend but not
for Extbase (for legacy and flexibility).

Greetings,

Christopher
