- evaluate "ScriptLoader loadOBApha" in latest #10246 - open a new browser and use "OBPackageBrowserAdapter" - in the browser select a package, then a class and click on the "UML Diag." in the button pane You should see a red rectangle with a yellow cross (draing error) due to a DNU on nil
I can confirm this problem. Its cause is probably outside OB I think, the same code works in Squeak. I can fix it in OB though. Also note that these visualizations such as UML do not get loaded or updated with #loadOBAlpha. You probably once loaded #loadSuperOB with which you indeed get Mondrian and OB-Mondrian-Diagrams that embed these visualizations to OB.
It also throws an error if no package is selected and the button is used.
oh, yes, this is an OB problem... I will fix it. David
