I've got two NSTokenFields. One is read-only as a palette for dragging and
dropping to the other. I've implemented a "Token" class to distinguish between tokens and plain text (NSString). I can pass in arrays of mixed Tokens and NSStrings, and it all displays correctly in both fields.
However, when I drag a token ("Token") from the palette to the field, it
arrives as a string and not a token. tokenField:(NSTokenField *)tokenField styleForRepresentedObject:(id)representedObject gets called with a NSString and not a "Token" class. I read somewhere you need to implement -
(void)encodeWithCoder:(NSCoder *)encoder and - (id)initWithCoder:(NSCoder
*)decoder on your Token, which I did, but they don't seem to get called.
Has anyone got any tips or example code?
