Trying to select a different service for an OpenShift 3 Server Adapter in Server Editor takes too long. After click on the Select... button it takes ~2-3 seconds to open dialog to select a different service. It would be ok to take it that time if there would be some indication that something is happening, but there is no job while "something" is happening.

Also clicking on the button multiple times (if it is not responsible, I clicked again and again and again), it takes a bit longer and open multiple dialogs.
