I thought your problem was that there were *too many* elements ;) Select the Configuration node > right click > Open Mapping Diagram - all entities should be shown. or Select all the entities you want to have included and right click, open Mapping Diagram all selected entiteis should be shown. You most likely just showed *one* entity. If the above doesn't work as you expect it to (i.e. if there are some associations you believe should be rendered but aren't, please open a bug report in jira!) Thanks!
