Comment #3 on issue 1001 by tu...@tudorgirba.com: Pharo: Moose: unable to get information from Dr. Geo packages. http://code.google.com/p/moose-technology/issues/detail?id=1001
Hmm, in your report you said that you tried with PetitParser* packages and got the same empty model.
But, now I tried exactly with DrGeoII packages. And indeed, the ui shows as if the model is empty. The model is actually not empty, but the UI is messed up. After a brief inspection, I see that there are some conflicts between Pharo and DrGeo in the Morphic and Polymorph-Widgets packages. In particular, the one in Polymorph-Widgets removes some TabMorph methods.
To fix it, reopen the Moose Panel after loading the Morphic package from Pharo again:
Gofer new url: 'http://ss3.gemstone.com/ss/Pharo20'; package: 'Polymorph-Widgets' constraint: [ :version | version author = 'MarcusDenker' and: [ version versionNumber = 780 ] ]; load
