Down arrow as indicator for existing content under an OpenShift 2 connection is not visible

If I have an OpenShift 2 connection which has been managed elsewhere (there is at least 1 domain under it) and I select Refresh in its context menu, connection is refreshed but there is no down arrow next to the connection tree item as indicator for expanding. Connection look still same, without any mark on its left side and user find out there is a domain only once he double click on the connection. The down arrow was there present earlier.
