             Summary: Improve BaseExplorerContentProvider.loadChildren()
                 Key: JBIDE-21216
                 URL: https://issues.jboss.org/browse/JBIDE-21216
             Project: Tools (JBoss Tools)
          Issue Type: Enhancement
          Components: openshift
    Affects Versions: 4.4.0.Alpha1
            Reporter: Viacheslav Kabanovich
            Assignee: Viacheslav Kabanovich
             Fix For: 4.3.1.Beta1, 4.4.0.Alpha1


This method may be called concurrently while children for current parentElement are being loaded. Now for this case implementation calls directly getChildrenFor(parentElement) which loads children in ui thread. So, if by some reason loading children in a separate job took a lot of time, by the same reason this second call in ui thread may hang Eclipse for some time.
Instead, it seams reasonable just to return the available loading stub as a child, when loading job is completed it will call refresh.
[~adietish] please take a look at the pull request.
