[TYPO3-mvc] Extbase Form Validation Error

[Christian Tauscher]

Hello.

A wrong filled out form gives out the error messages correctly.
On Top of the Error Block is this Line:

** An error occurred while trying to call Tmd\Screenprinting\Controller
** \PrintitemController->updateAction()

How to manipulate/translate this Line?

Did not find solutions for this.


Thank you a lot,

Christian.
