    Description

      In openshift explorer, when scaling a service that has 2 deployments, it deploys pod from the oldest deployment instead of the latest. Eventually, these pods are killed by openshift.

      The workaround is to open the properties view and issue a scale command on a deployment directly.

      However, because scaling is such a front-and-center feature from the explorer, I believe it's critical we fix it ASAP

      (copied from JBIDE-23412)
      The following steps can be seen in the following screencast:
      scale-to-shows-old-rc.ogv

      1. ASSERT: have an app running (ex. nodejs-example)
      2. ASSERT: In OpenShift Explorer: make sure it has at least 1 pod: pick "Scale To" in the context menu of the service. Dialog shows that there's at least 1 pod currently
      3. ASSERT: in OpenShift Explorer: there 1 pod shown as child to the service.
      4. ASSERT: in Properties view, pick "Deployments" tab and see that there's at least 1 deployment (aka replication controller)
      5. EXEC: in OpenShift explorer: select Service pick "Deploy Latest"
      6. ASSERT: in Properties view: "Deployments" now shows 2 Deployments
      7. ASSERT: in OpenShift Explorer you now see 2 children/pods
      8. EXEC: in OpenShift Explorer: pick "Scale To..." in the context menu of the service

      Result:
      The current number of pods is shown as 0.

      But it's very sure that this is not true. Behind the scenes a new replication controller was created which deployed a new pod:

      The old replication controller was turned to have 0 pods. The "Scale To" dialog shows the number of replcas for the old replication controller.
