Eclipse behaves strange here. I've updated everything. And "Mark Occurrences" works in a normal Java editor, but it does not in and xtend-editor.
Do you have any information what's the reason for that? Is this a bug?
I've also tried to use the workaround to select something in the outline and switching back to some variable. The workaround doesn't work either.
My Eclipse is running on a Windows 10.
