Hi

I am very close to implementing write (finally!!). Just one thing
stopping me.
When I do a save operation, I get this message in the writeToFile
method

*** -[GMDataBackedFileDelegate longValue]: unrecognized selector sent
to instance 0x16cb30f0

I am using an implementation similar to the one in LoopbackFS and
assigning an NSNumber to the fileDelegate property when a file is
created.
I understand that this would happen if the value for fileDelegate was
not retained. Or is there some other problem?

Thanks.
