I have a Core Data app that has several entities. One entity, Window,
contains several properties such as openAtLaunch, windowName, and
wController. The wController attributes are Transformable, Optional
and Transient. The data are presented on a list, and when the user
double-clicks a record, a window controller is allocated and set as
the value for the property wController and then the window controller
is released, giving it a retain count of 1.
However, and this is the weird part, whenever I change another
property of the Window managed object, such as the openAtLaunch value,
the window controller receives a 'retain'. Even if I just edit the
windowName property, the wController value (the window controller)
gets another retain. So by the time the user wants to delete a
managed object from the list, the window controller could have a high
value and is never released!
My question is, why would changing a property value cause another
property to have its retain count increase?
Any insight would be appreciated.
Thanks.
