Hello,
I have a NSTableView with a column of checkboxes. I have the checkbox value bound to an NSInteger instance in a class which is in an array bound as the content to an array controller. When the program starts the column is filled with 16 rows and the checkbox is set to off. Other columns with bindings seem to work OK, but the checkbox column gives the error
Cannot create BOOL from object (
0,
0,
0,
0,
0,
0,
0,
0,
0,
0,
0,
0,
0,
0,
0,
0
) of class NSCFArray
This column is not bound to a core data managed object. The other columns are. I can get rid of this error if I remove the binding on the other columns that are bound to core data managed objects.
So, the question is can a TableView have columns where some columns are bound to core data managed objects and others to unmanaged objects? If not, then is there a way to prevent changes to a managed object from causing the document from being tagged as dirty and triggering the "Save" dialog when closing?
If mixed bindings are allowed, any idea what I am doing wrong?
Thanks
