Hi,
I have a problem with CoreData. I'm pretty new to CoreData so this
question might be dumb.
The first step in my app is to fetch a XML and put it in to CoreData.
This seems to work, as the .xml in the app-folder in
ApplicationSupport looks good. Everything appears where I expect it.
In the app those values should be displayed in a NSTable. So I added
an ArrayController to handle the data.
In the "ObjectController"-Section of the ArrayController I set Mode to
Entity and Entity Name to the Name of the Entity in my datamodel. In
the bindings section I set Parameters for "Bind to" to the AppDelegate
and the "Model Key Path" to "managed Object Context".
For a first test a I set up only one table column. In the Value-
Section of the Binding-Properties is set "Bind to:" to the
ArrayController, ControllerKey to "arrangedObjects" and the "Model Key
Path" to a Propery of the Entity which has, according to the xml in
the appSupport folder, definitely more than on valid value.
When I now fire the App table row is and remains empty :(
Did I forget to make some settings?
Thank you very much in advance.
regards,
matthias
