[Pharo-project] Loading Gemstone Variable (Indexable) classes into Pharo via Monticello
I have the following in Gemstone: FristClass which is a indexableSublass of Object. SecondClass which is a subclass of FirstClass. When I save this to Monticello and then load it into Pharo, the load fails on the 'recompile' because the SecondClass is not of type #variable. The load works when I modify the method MCClassDefinition>>createClass to use the superclass' type when the superclass type is #variable. --- current way ---- ... type: type; ... --- hacked way ---- .... type: ((superClass typeOfClass isSymbol not and: [superClass typeOfClass isVariable]) ifTrue: [superClass typeOfClass] ifFalse: [type]); .... With this I was sucessfully able to important the code into Pharo. I am able to go from Pharo to GemStone with no problems. Is there a general solution to this problem? It obviously will not occur very often. Regards, Reg

can you check the fix for the classbuilder in the bug archive and let us know if it fixes the problem? http://code.google.com/p/pharo/issues/detail?id=1270 I guess not. Now I'm wondering how the other smalltalk react to a variableSubclass being subclass. Did you try? Finally what you should know is that the classBuilder in Squeak/pharo is really an ugly beast that one of these will have to be rewritten from scratch Stef
