Hi everyone,
Has anyone had any trouble with NSPredicate causing occasional crashes when
used with NSArrayController? Well actually about 50% of the time.
What I have is a subclass of NSArrayController which is a data source for an
NSTableView that accepts drag and drop operations. In 'awakeFromNib' a
NSPredicate is defined, sometimes the error is just, “EXC_BAD_ACCESS”, other
times there's a bit more info:
data_source.rb:20:in `awakeFromNib': NSInvalidArgumentException: Unable to
parse the format string "AND" (RuntimeError)
This is the offending line:
@filter_predicate = NSPredicate.predicateWithFormat("file_type ==
'NSFileTypeRegular'")
The crash doesn't always occur, when it doesn't my app works without any
problems. I've tried the predicate in macirb and the crash doesn't occur!?
Best regards,
Alan_______________________________________________
