[TYPO3-mvc] filter for frontend user in isValid validator

[Domi]

Thanks Claus,

I tried almost everything. Its an 6.0 and here is the sql output:

SELECT  fe_users.* FROM fe_users  WHERE fe_users.uid = '1' AND 
(fe_users.tx_extbase_type='TYPO3\\CMS\\Extbase\\Domain\\Model\\FrontendUser') 
AND fe_users.deleted=0 AND fe_users.disable=0 AND 
fe_users.starttime<=1358181840 AND (fe_users.endtime=0 OR 
fe_users.endtime>1358181840) LIMIT 1

Now I am confused with the tx_extbase_type. In the database 
Tx_Extbase_Domain_Model_FrontendUser is set in the column of the extbase 
type.

Do I need to set the new type in every tx_extbase_type column?

Thanks,
Dominic
