Description Nobody - feel free to take it CLA 2011-09-21 10:48:12 EDT 
Steps to reproduce:

1. Start Eclipse in C/C++ perspective and set "Windows->Preferences->Run/Debug->Perspectives->Open the associated perspective when an application suspends" option to "Prompt".

2. Open the Debug view

3. Start a debug session. 

4. The "Confirm Perspective Switch" dialog will appear. Wait until the Debug view is fully populated and press "Yes".

The debugger related actions (Run To Line, Resume At Line, Move To Line, Add Watch Expression) are not is the editor's context menu as expected. Selecting an entry in the Debug view will make them appear.

The reason this is happening is at some point when the perspectives are switching the selection in the Debug view is reset. This results in the reseting of "debuggerActive" property in 'EvaluationContextManager' which controls the visibility of the debugger actions.

Proposed fix.
Comment 2 Anton Leherbauer CLA 2011-09-22 04:42:19 EDT 
It seems on perspective switch an empty selection change for the Debug View gets triggered by the Debug View Breadcrumb, even though it is not visible.
This could also be related to bug 358382.

Comment 3 Pawel Piech CLA 2011-09-22 11:15:38 EDT 
Something similar has been reported in the past (bug 329049).  I'll try to take a look at it soon, since I guess someone out there is using the debug breadcrumb besides me ;-)
Comment 4 Pawel Piech CLA 2012-04-02 17:59:37 EDT
