I have a program that implements a number of
tableviews in an NSDocument setting. Two of the
tableviews have content that is document independent;
only the selection changes from document to document.
I read the data in from a file in a delegate of my
MainMenu.nib and use this delegate.array as my content
array. The NSArrayController and NSTableView are in
the document .nib file. When I run my program, I get
this message:
2005-10-08 15:13:27.602 WarbandDef[2684] *** Illegal
NSTableView data source (<NSArrayController:
0x3dedf0>[object class: SkillTypeDef, number of
selected objects: 0]). Must implement
numberOfRowsInTableView: and
tableView:objectValueForTableColumn:row:
The program does run fine and I can select Skill Type
values for different warbands. I've been ignoring
this message while I fix other things since it seems
to work. I'm now looking into this. I can't
determine what, if anything, I can/should do to clean
this up.
Can I ignore this warning? If not, why's it being
generated when NSArrayControllers handle these methods
behind the scene?
