1. ReferenceStream newFileNamed:do: does not exist in base. 2. newFileNamed: can return nil, if it can't open a file stream, even after GC. 3. This usually implies too many file handles are open. 4. The best thing that can be done in core, is probably to raise an error in DataStream newFileNamed: if the opening of the underlying stream fails, but that won't really solve your problems. i.e., this is most probably an application error caused by not closing file streams so creating new ones fails.

PS: the title of this thread would be much better if you went a step down, ie: "stream can be nil in DataStream setStream:". "UndefinedObject doesNotUnderstand: #binary" really tells nothing about what/where the error actually occurs. Cheers, Herny

"UndefinedObject doesNotUnderstand: #binary" really tells nothing about what/where  the error  actually occurs.
Sorry about that, I think I sent the stack trace from the image and it wasn't clear what would happen precisely from the UI. Now I don't remember exactly but that image had been confused about files in other places. Since then we rebuilt one from scratch and now it works.
