> If the Form containing the AbstractAutocompleteTextField and the TextField after the else-block has been executed the ModelObject of TextField is NULL no matter what Value is filled in. All other fields ModelObjects of the form are filled correctly. 
> Form submitting does not fail when else-block was not executed.
> ModelObject of the form is a CompoundPropertyModel of "Obj".
