1. EXEC: Create Runtime and Server by New->Server action on server view
2. EXEC: Open Server Configuration Editor by double click on server created before in server view
3. EXEC: Delete created server by Delete item in context menu
4. ASSERT: Server deleted and Configuration editor is closed

Now it editor stays ope and it is confusing in some cases. If you have many editors open and Server Configuration editor was changed is is easy to get to situation, when finally you get to the point of closing it. When editor with changes is closing it asks about saving changes. If you says yes on this request for editor that left open after test case above it saves deleted configuration and restore deleted server in server view.
