Actually the other way around in this case ... the snapshot cache is
expecting to contain NSMutableArrays, but you've somehow managed to
get an NSArray in there. Are you doing something weird like manually
replacing the array in a to-many relationship or something?

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!!!
