GNUstep complies with the documented behaviour it seems that while mac osx may comply with the documented behaviour, it has some sort of magic default formatters to format everything (i don't quite understand this since formatters work with strings and not objects)... anyhow IMHO the documentation of the implementation isn't as important what the developer can expect to happen/be returned when calling a method, and in that regard their documentation *was* broken last time i looked at it at least. i can't actually figure out how to make -hasValidObjectValue return NO on a mac :) so this issue doesn't seem to be limited to attributed strings... attached test program, and below is output... matt (make -f Makefile on a mac) GNUstep: 2005-07-21 18:37:02.000 cellTest[11056] -objectValue=(nil) KindOf=(nil) formatter=(nil) hasValidObjectValue=NO 2005-07-21 18:37:02.000 cellTest[11056] NSAnyType 2005-07-21 18:37:02.000 cellTest[11056] -objectValue=(nil) KindOf=(nil) formatter=(nil) hasValidObjectValue=NO 2005-07-21 18:37:02.000 cellTest[11056] NSAnyType 2005-07-21 18:37:02.000 cellTest[11056] -objectValue=(nil) KindOf=(nil) formatter=(nil) hasValidObjectValue=NO 2005-07-21 18:37:02.000 cellTest[11056] NSAnyType 2005-07-21 18:37:02.000 cellTest[11056] 23 23.500000 23.500000 2005-07-21 18:37:02.000 cellTest[11056] -objectValue=(nil) KindOf=(nil) formatter=(nil) hasValidObjectValue=NO 2005-07-21 18:37:02.000 cellTest[11056] NSAnyType 2005-07-21 18:37:02.000 cellTest[11056] -objectValue=(nil) KindOf=(nil) formatter=(nil) hasValidObjectValue=NO 2005-07-21 18:37:02.000 cellTest[11056] NSAnyType Mac: 2005-07-21 18:21:35.390 cellTest[4791] -objectValue=55 KindOf=NSCFNumber formatter=(null) hasValidObjectValue=YES 2005-07-21 18:21:35.391 cellTest[4791] NSAnyType 2005-07-21 18:21:35.392 cellTest[4791] -objectValue=<Foo: 0x527160> KindOf=Foo formatter=(null) hasValidObjectValue=YES 2005-07-21 18:21:35.393 cellTest[4791] NSAnyType 2005-07-21 18:21:35.394 cellTest[4791] -objectValue=23.5 KindOf=NSCFNumber formatter=(null) hasValidObjectValue=YES 2005-07-21 18:21:35.395 cellTest[4791] NSAnyType 2005-07-21 18:21:35.396 cellTest[4791] 23 23.500000 23.500000 2005-07-21 18:21:35.398 cellTest[4791] -objectValue=zxcv{} KindOf=NSConcreteAttributedString formatter=(null) hasValidObjectValue=YES 2005-07-21 18:21:35.399 cellTest[4791] NSAnyType 2005-07-21 18:21:35.400 cellTest[4791] -objectValue=(null) KindOf=(null) formatter=(null) hasValidObjectValue=YES ____________________________________________________ Start your day with Yahoo! - make it your home page http://www.yahoo.com/r/hs
