The line
set theValue to theObject's valueForKey_(".title")
yields this in console:
2009-09-24 11:28:33.319 backupC[1154:a0f] *** -[backupCAppDelegate testclick:]: [<Backupset 0x20009db80> valueForUndefinedKey:]: this class is not key value coding-compliant for the key properties.title. (error -10000)
The key is defined in the array controller key list as well as the properties instance of NSMutableDictionary.
I wonder if we are accessing the Dictionary object or something else with
set theObject to mySelectedObject's objectAtIndex_(0)
