[TYPO3-mvc] How to use FrontendUserGroup ?

At first, you should inject the  
Tx_Extbase_Domain_Repository_FrontendUserGroupRepository and not make an  
instance in initializeAction. You'll find an example of dependency  
injection here: http://goo.gl/IuKNV (see injectFrontendUserRepository  
method)

Then $this->frontendUserGroupRepository->findAll(); should return all  
groups, which have the record type set to  
Tx_Extbase_Domain_Model-FrontendUserGroup (this can be done in T3 backend).

The assignment to template should work now.

Kind regards
