Proble solved! There was an error in my getter method for the concerned
entity!

Hi,
i have some issues trying to save an Entitie in the database after
filling the coresponding form. In fact i figured out that the
Entity(Object) is Null after a press the save button of the form. This
is confusing because I do not have this effect with other entities and
forms of my application.
Debug took me to the LoggingAdvice.class. Any idea what i am doing wrong?
Thanks!
Will
