I am having trouble creating and using a custom table view cell.
I added a new cocoa obj-c file MyCell. The MyCell class derives from NSCell and does its own drawing (drawInteriorWithFrame:inView:).
I get the following error message at run time.
---
Error invoking selector openAccountWindow on key path selection of object <NSTreeController: 0x10015f8e0>[object class: NSMutableArray] (from bound object <NSOutlineView: 0x1001563e0> with object ID 100022 in nib named MyDocument.nib): [<NSTableColumn 0x10055c460> valueForUndefinedKey:]: this class is not key value coding-compliant for the key value.
---
I have implemented the method "value" and setValue: in MyCell. So I am confused as to why I see this error.
Note: my program has a tree view which launches a table view in a separate window when double clicked. That is why there is a reference to NSTreeController above.
If I change MyCell to inherit from NSTextFieldCell I do not get this error. But I would like to understand why this error happens when MyCell inherits from NSCell.
Thanks
