Hi Sergio, I have used Fuel to good effect to store a tree of objects (with all interlinkages).
Saving: saveTo: aFileOrName | aFileName | aFileName := aFileOrName fullName. FLSerializer serialize: self toFileNamed: aFileName Loading: loadFrom: aFileOrFileName | new | new := FLMaterializer materializeFromFileNamed: aFileOrFileName fullName. new ifNil: [^nil]. "becomeForward fails for nil!" self becomeForward: new Just make sure you don't have any references to objects outside of your model tree - you'll disappear down a black hole as it tries to save the whole image!
