[TYPO3-mvc] update an existing fe_user without editAction

[S.Korth]

> I can't figure out what's the problem here. When i print_r the $exisitingUser object it has a value for uid.

Hey Kevin,

iam new to extbase, but as far as i know, the update function does the 
same as the replace funktion. The update function gets the uid from the 
existing object for you and calls the replace function.

What does $newUser->getUid() say ? I think if you want to update or 
replace an Object it needs also an uid.
