[jbosstools-issues] [JBoss JIRA] (JBIDE-21828) OpenShift Explorer view flickers when refreshing a service

[Jeff Cantrill (JIRA)]

    [ https://issues.jboss.org/browse/JBIDE-21828?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13174224#comment-13174224 ] 

Jeff Cantrill commented on JBIDE-21828:
---------------------------------------

It sounds like the short term solution that may resolve much of this is to revert the changes in the ConnectionRegistry to not notify async.  This was something I added as part of making the delete project issue go away, but I don't believe it is integral to a solution for that.  There are probably better ways to manage the content provider and this may be one of them; I have never been fond of the design.  My suggestion is to start with reverting the changes and work towards these other changes as a refactoring effort, if they make sense.

> When calling the "Refresh" command on a service, the tree view flickers because of too many refresh calls.
> Adding some traces revealed 25 calls to {{BaseExplorerContentProvider#refreshViewer(Object)}}, which seems way too much for a service with a single pod.
> Attachement: screenshot of the OpenShift Server view, showing 2 projects, one of which has 3 services.
> Custom/added logs in the console:
