Can you please clarify if you see the CodeLive Dashboard after reloading/refreshing the page in the browser?
Disabling CodeLive on the server automatically redeploys the project and you will have to refresh/reload the page in the browser to remove the dashboard.
If the issue persists, please share with us the .log file located at workspace dir/.metadata/.log for further investigation.
We realize that you are not working with the in-built JBoss connector. We could replicate the problem with Red Hat JBoss EAP 6.1+ connector installed into MyEclipse. The dev team is looking into a workaround.
The problem you reported with the CodeLive Dashboard does not occur in the in-built JBoss connectors. Alternatively, you can configure the JBoss EAP 6.4 using our in-built JBoss connector, JBoss AS v7.x (New > Server > JBoss AS > JBoss AS v7.x). When configuring JBoss EAP server using the JBoss AS connector, you will see a warning that the installation directory is not a valid JBoss Runtime. You can ignore the warning and go ahead with the configuration.
