Hi,

I'm using Eclipse 4.2 with SWTBot 2.0.5 for testing my application.
On trying to click on a tree item specific context menu in a view, it's throwing java.lang.reflect.InvocationTargetException.

Not all context menu of view throws the exception but only those context menu which gets enabled only after selecting the tree item.

Before testing, i made sure that the tree item is present in the view and selected.

Below is my code:
NOTE: The below lines of code works fine in Eclipse Indigo

// At this point, the active view returned is Variable view
SWTBotView activeView = bot.activeView();
// At this point, Variable View has the variable already loaded and it's selected
SWTBotTreeItem item = view.bot().tree().getAllItems()[0].select();
// We try to click context menu 'Change Value...'
// which are enabled after selecting tree item
item.contextMenu("Change Value...").click();

At the above last line, below is the exception that is being thrown:

Hi,

It seems to me that the issue you describe is the one that was reported
here: https://bugs.eclipse.org/bugs/show_bug.cgi?id=384621
Fortunately, it is already fixed and the fix will be part of next SWTBot
release. In the meantime, you can use the SNAPSHOTS of SWTBot which
already contain this fix:
