Description Marc-André Laperle CLA 2012-02-06 12:50:59 EST 
Using eclipse-cpp-juno-M5-win32-x86_64

1. Create a hello world project
2. Build the project
3. Debug the project, it should stop at main
4. In the Debug view, in the tree, click on the thread or process, then on the Step Instruction button. Nothing happens.

With 3.8M5, when the button is pressed, the button becomes enabled, the disassembly view opens and step over steps through instructions in Disassembly view.

The action doesn't seem to be checked so the code doesn't even up showing the view.
Comment 3 Remy Suen CLA 2012-02-07 08:40:54 EST 
In 3.x we don't go through the ActionDelegateHandlerProxy so we don't get another call to selectionChanged(*) which prevents the action from thinking it is unchecked.
