With an instance of PatchArchiveClient openInWorld, I attempt to change the class from SystemWindow subclass: #PatchArchiveClient To Model subclass: #PatchArchiveClient When I do this I get the white screen of death (The WSoD doesn't appear to produce an error log and I haven't figured out how to debug in this situation.) It shows a ***system error handing failed **** Original Error: Message not understood PatchArchiveClient>>full bounds. Debugger Error: Message not understood PatchArchiveClient>>isDockingBar:[]in DebuggerClass>>openOn:context:label:conents:fullView:{[:ex | self primitiveError: 'Oringinal error:' , title as......
It makes sense that PAC would no longer understand fullBound once it's changed from System Window to Model. The problem doesn't occur when I do not have PatchArchiveClient open, so this isn't a big deal. I'm reporting it because in Squeak I hope that I can change objects on the fly with nothing worse happeing than a Debugger Window. Wouldn't expect that anywhere else, course. Maybe changing the inheritence structure is just going too far?
(This was I Squeak3.8a-63905.unstable-image but the same sort of thing happens in Squeak3.7g-5976.image. I'm runing Win XP Pro. )
