    [ https://jira.jboss.org/jira/browse/JBIDE-6145?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12523799#action_12523799 ] 

Viacheslav Kabanovich commented on JBIDE-6145:
----------------------------------------------

The issue was found while working on JBIDE-5746. It is related to it, but requires separate solution.

VpeEditorPart activates three handlers (org.jboss.tools.vpe.visual.maxmin, org.jboss.tools.vpe.source.maxmin, org.jboss.tools.vpe.jumping) in ActivationListener (implemenst IPartListener). Debugging studio, I have found that when the described steps are exactly repeated, method partActivated for the first editor is invoked twice, which results in duplicate activation of handlers. After that, when the second editor is activated, deactivation of the first editor turns out ineffective. That looks like a problem of Eclipse, but there is a simple work around for us.

Restart studio and make sure that on opening it activated xhtml file and the second one is present as an inactive tab.
