Hi All, Attempting to load DataFrame with: Metacello new baseline: 'DataFrame'; repository: 'github://PolyMathOrg/DataFrame'; load. results in what looks like a stack trace being displayed on the window background. See the attached image. The system is unresponsive until interrupted (Ctrl-. on linux). The stack in the image appears to match the stack included below from MorphicUIManager>>onPrimitiveError: onwards. I'm not at all familiar with this code, but it looks a bit like the load has failed, and then the attempt to trap it and open a debugger has failed. One of the failures, at least, appears to be because the Roassal2Spec package overrides the inherited definition of #announcer in NewValueHolder to remove the lazy initialisation. However the NewValueHolder>>announcer extension has been there for a couple of years, so I presume it is some other change that has triggered the problem. Can someone, Alexandre? :-), comment on whether NewValueHolder>>announcer should be removed?
