I am using LUNA SR1 (4.4.1) and CDT head code base with SWTBOT 2.2.1
Attempting a simple test to click a context menu item on a expression that is available on debugger expression view is leading to an exception from the platform code. Exception stack trace is as follows .

This exception says that menu.add(getAction(FIND_ACTION));

is causing the trouble . Method getAction() is unable to get "Find" action object. But if I am doing it manually this exception is not coming. I debugged that part of code and when doing manually method returns a valid object and when running through SWTbot method returns null.

My test code is which gets into trouble is show below

private void disableExpression()
{
SWTWorkbenchBot vbot= new SWTWorkbenchBot();
SWTBotView vv=vbot.viewByTitle("Expressions");
vbot.sleep(1000);
SWTBotTree expressionTree = vv.bot().tree();

//expressionTree.
expressionTree.select("x_mfa"); // select the the expression that is existing
vbot.sleep(100);
expressionTree.contextMenu("Disable");
}

Did any one try context menu on CDT views or debug views like Variables , Expressions etc. on LUNA ? Any idea while running with SWTBot this happens but not when manually accessing the context menu?

Any help is much appreciated
Thanks

Can you try the following

private void disableExpression()
{
SWTWorkbenchBot vbot= new SWTWorkbenchBot();
SWTBotView vv=vbot.viewByTitle("Expressions");
vbot.sleep(1000);
SWTBotTree expressionTree = vv.bot().tree();

//expressionTree.
expressionTree.select("x_mfa").contextMenu("Disable");
}
