Hi all --
I have a method in my app delegate that is registering two value
transformers, the first registration compiles fine, but I get a
warning on the second registration that says:
warning: passing argument 1 of 'setValueTransformer:forName:' from
distinct Objective-C type
I've seen this kind of error when I forget to make an object a
pointer or something silly like that, but in this case I can't figure
out what's wrong even after spending a great deal of time messing
around with it.
Any help would be appreciated.
Thanks very much.

ValuePlusOne *valuePlusOneTransformer;
ColumnNameToIcon *columnNameToIconTransformer;
valuePlusOneTransformer = [[[ValuePlusOne alloc] init] autorelease];
[NSValueTransformer setValueTransformer:valuePlusOneTransformer
forName:@"valuePlusOne"]; // this works
columnNameToIconTransformer = [[[ColumnNameToIcon alloc] init]
autorelease];
[NSValueTransformer setValueTransformer:columnNameToIconTransformer
forName:@"columnNameToIcon"]; // warning here
}
