Hi. Fuel does support full serialization of closures� but you may need to "enable" that.
BTW, can you try something with the image where you still have the closure and try to serialize this way:

| serializer |
serializer := FLSerializer newFull.
serializer serialize: xxx on: aStream.

and tell me if that also work?

This bit in a workspace also raises an error. I'm not sure why it does and I don't know why you'd ever do it in practice:

|coll|
coll:=OrderedCollection new.
(Interval from: 1 to: 100) do: [:each|

� � � � � � � �ifTrue: [SortedCollection sortBlock:[:a :c | a name < c name] ]
� � � � � � � �ifFalse:[Dictionary new] ) ].

FLSerializer serialize: coll toFileNamed: 'collection.fuel'.

FLMaterializer materializeFromFileNamed: 'collection.fuel'

Thanks, I could reproduce it. I will take a look soon.

that looks weird, because you are materializng in the SAME image ...

which class is the one that contains that #initialize?
do you have an #initialize in your image that uses pragmas?

can you try closing all opened ssytem browsers (nautilus windows or

is your data private or you can provide an image with "users" so that we
