Looks like the Find action is being removed from the global action map after a certain set of actions.

Some steps I used to reproduce:
1. debug a simple app, with vars you can edit while debugging
2. when suspended, go to the var view
3. click a var entry to start editing it
4. without ending the edit, right-click on the column header of another column

Mike,
I agree that we should investigate on why "Find" is removed on Mac. But till that is found , should we not add a null check before adding Find action ?

That makes sense.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. As such, we're closing this bug.

If you have further information on the current state of the bug, please add it and reopen this bug. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.

Comment 8 Andrey Loskutov 2022-02-10 11:47:46 EST

And, btw, there *was* the "Find..." action in the context menu.
It seem randomly appear while I'm right clicking on variables, but I see no pattern what causes the error...

Not a fix, just want see if the global actions map was entirely empty (would mean somehow focusLost() clears that via org.eclipse.debug.internal.ui.views.variables.VariablesView.clearGlobalActions()), or something else is going wrong.
