Saving objects with BOSS is fairly simple if you exclude any GUI issues; the code below will suffice:

	file := filename asFilename writeStream.
	[bos := BinaryObjectStorage onNew: file.
	bos nextPut: data.
	file close]
		on: self bossExceptions
		do: [:ex | file close.
			result := false.
			ex return].
	file close.

That will fail if the object(s) you save have any hold on screen objects though; you cannot BOSS out platform speccific GUI objects. The most common way that comes up is via dependency. So - today I go through an example of how to deal with that, using BottomFeeder code to demonstrate. Click on the image below to watch:
