Usually if some vertices are visible, the browser tables below show only data related to the current context. Clicking on an item in the table will result in a visible vertex beeing selected.
However, if no vertex is shown (and therefore the famous *No Vertices in Focus Window* is shown), the browser tables below show ALL available information. In case of Linkd Topology Provider it would show all existing Alarms and Nodes. If a user now clicks on an item, it gets selected accordingly (the info panel shows the selected information). Unfortunately the vertex was not visible before and is not visible afterwards. The table below is also filtered. The only choice now is to either go back or switch Topology Providers back and forth.
The correct behaviour from my point of view should be, that if a element is selected from the browser table below, and that element is not visible at the moment, it is added to the current focus.
