Make sure the field editor isn't getting in the way. The field
editors inserts itself into the first responder chain and grabs
textual input during editing.

Anyone know how best to use multiple NSTextCell subclasses, in a
table/outline column?
When I use the dataCell... methods in NSTableColumn, NSTableView,
or NSOutlineView, it works great until I try to edit the cell, at
which point the cells never receive the edit/select actions. I've
tried lots of things but can't figure out what's happening, nor a
better why to do this overall.
In other words:
When I use the dataCellForTableColumn method, my table does display
the different textcell subclasses returned. But when I send the
table/outline [self editColumn:1 row:[self selectedRow]
withEvent:theEvent select:YES] message it seems to get lost -- my
specified cells don't receive an editWithFrame/selectWithFrame
action. If I remove this method and only use one cell class in the
column, it works as expected.
- (NSCell *)outlineView:(NSOutlineView *)outlineView
dataCellForTableColumn:(NSTableColumn *)tableColumn item:(id)item {
if ([item isKindOfClass:[Project class]]) return projectTextCell;
if ([item isKindOfClass:[Action class]]) return actionTextCell;
if ([item isKindOfClass:[Item class]]) return itemTextCell;
if ([item isKindOfClass:[Note class]]) return noteTextCell;
return nil;
}
The point of this is to breakout my cell designs for efficiency and
comprehension. But so far it's just making me nuts. ;-).
