[jbosstools-issues] [JBoss JIRA] (JBIDE-17624) (un)checking Early Access while refreshing the connector logs an org.eclipse.swt.SWTException

[Snjezana Peco (JIRA)]

    [ https://issues.jboss.org/browse/JBIDE-17624?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12981090#comment-12981090 ] 

Snjezana Peco commented on JBIDE-17624:
---------------------------------------

The issue happens if you click the "Show Early access" action while the Central editor is refreshing the page.
The issue isn't OS specific. All you need to do is to click the action quickly.

The PR fixes the issue by disabling the "Show Early access" action (as well as "Select All"/"Deselect all" actions) during refreshing.
