Name: Tools-fbs.283 Author: fbs Time: 1 December 2010, 3:09:44.682 pm UUID: 810789fa-9417-a340-a578-0df71274f43d Ancestors: Tools-ul.282
When a method changes out from under your feet in the Debugger (e.g., you remove an instvar triggering a recompile of a method through which you've stepped), the Debugger blanks out contents. In the UI, this manifests as a blank code pane.
This change resets the contents ivar by setting it to the new, recompiled, CompiledMethod as a side effect of calling self selectedMessage.
=============== Diff against Tools-ul.282 ===============
