[Pharo-users] DNU on materializing a fueled out exception

[Holger Freyther]

Hi,

I showed Pharo to a friend and wanted to show the nice feature of fueling out 
an exception and then using FLMaterializer class>>#materializeFromFileNamed: to 
load it back and get a debugger up. In Pharo5 I am presented a DNU instead.

The DNU is on GTGenericStackDebugger as it doesn't understand the message Fuel 
is sending. What to fix, Fuel to use the new protocol or GTGenericStackDebugger 
to honor the old protocol?

FueldOutStackDebugAction>>#serializeTestFailureContext: aContext toFileNamed: 
aFilename
        | serializer |
        
        serializer := FLSerializer newDefault.
        self encodeDebugInformationOn: serializer. 
        serializer addPostMaterializationAction: [ :materialization | 
                Smalltalk tools debugger
                        openOn: Processor activeProcess 
                        context: materialization root 
                        label: 'External stack' 
                        contents: nil 
                        fullView: false ].

So it looks like now it should create a debug session first and then pass it to 
the debugger? I think loading new fuel in Pharo3.x is still possible so maybe 
it is best to re-add that protocol?

comments?
