/**
* A special action which is called if the originally intended action could
* not be called, for example if the arguments were not valid.
*
* The default implementation sets a flash message, request errors and forwards back
* to the originating action. This is suitable for most actions dealing with form input.
*
* We clear the page cache by default on an error as well, as we need to make sure the
* data is re-evaluated when the user changes something.

Got the error now... BUT! If I clean my cache from Backend (the 3) then everything works as expected... how can this be a validation problem? ANy Idea?
