Hello Daniele,
I'm sure someone will come with more help, but just in case, are your
sure you're getting a NSArray?
Usually a ClassCastException is thrown if you get something else than
the class that was defined. You're not passing NSMutableArray instead?

support.gestweb.component.insert.GWSAddDiscount.create simply takes
my EnterpriseObject GWSDiscount, controls if my form has populed
the fields, then, if is a new instance, inserts it in the EC, after
call _saveChangesAndFIxObjects(). This method simply control if
every objects in the ec satisfy the requisitions, if not the object
is deleted, in the end the method calls ec.saveChanges();
I'm quite sure the object is not deleted, so I have no idea why
this error is fired.
Has anyone encountered it before?
Thanks for help!!!
