Scenario I have a list, when I select an element from the list, its properties, visu and metrics are shown by glamour. Ideal Situation: I trigger the selection of a random node (from another visu) and its not part of the shown elements in the list (but is still part of model), it should be selected/gets focus in the list. what this "Fix" does With the "fix", I can see the properties and visu of the selected node in my browser and DNU is gone.

Re: [Pharo-project] Cross-classified methods

by Stephan Eggermont

Hmm, it was not clear in which direction this works. I switched them for http://code.google.com/p/pharo/issues/detail?id=7379 Thanks for noting, Sean. So: the first set are methods where Squeak has no classification, and Pharo does. The second set has methods where Pharo has no classifications, and Squeak does. Stephan
