The OpenShift Express Console allows you to delete applications, create new applications and will allow you to refresh the view. Those operations are executed in background jobs so that the Eclipse UI is not blocked in the meantime. We therefore have to setup scheduling rules on those jobs so that a refresh will wait until the delete is finished. To me the best way to achieve this is to create cathegories of jobs (ex. ApplicationJob, UserJob, etc.) that have the appropriate scheduling rules initialized (ex. ApplicationJobs operate on applications and therefore have to block UserJob that possibly operate on all applications.)
