    [ https://issues.jboss.org/browse/JBIDE-21665?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13163169#comment-13163169 ] 

Jeff Cantrill commented on JBIDE-21665:
---------------------------------------

[~adietish] I think refreshing before scaling is probably a reasonable solution but there is an underlying bug here which probably is pervasive across the plugin.  We should have received a change notification from the watch, but we probably don't reasonably guarantee that we have the latest version of a resource.  Since we are mostly readonly, this generally isn't an issue, but we should probably do a GET before we take any action that requires us to update a resource.  The larger question might be how to ensure that 'get' is propagated to all the listeners.  This change https://issues.jboss.org/browse/OSJC-238 is probably the one that gets us towards it.
