Okay, so I'm drawing an utter blank on how to use this in AppleScriptObjC.
How do you refer to [sender tag]?
If I try:
set theTag to sender's tag()
or
set theTag to sender's tag_()
I get:
2011-04-07 12:56:52.678 Derby Score[1998:903] -[NSDragDestination tag]:
unrecognized selector sent to instance 0x20009d620
2011-04-07 12:56:52.716 Derby Score[1998:903] *** -[MyImageView
performDragOperation:]: -[NSDragDestination tag]: unrecognized selector sent
to instance 0x20009d620 (error -10000)
If I just try:
set theTag to sender's tag
I get:
2011-04-07 12:59:18.250 Derby Score[2063:903] *** Canceling drag because
exception 'NSUnknownKeyException' (reason '[<NSDragDestination 0x2006d2c60>
valueForUndefinedKey:]: this class is not key value coding-compliant for the
key tag.') was raised during a dragging session
What am I missing here?
