When setup Liferay 6.1.0 Bundle with JBoss using non-default context path(ROOT). The session is inconsistency in ZUL file and in DHtmlUpdateServlet.
Steps to change context path:
1. Download and install Liferay 6.1 GA + JBoss bundle from liferay.com (liferay-portal-jboss-6.1.0-ce-ga1-20120106155615760.zip)
2. In jboss-7.0.2 folder:
o Rename folder standalone/deployments/ROOT.war to standalone/deployments/intranet.war
o Rename file standalone/deployments/ROOT.war.dodeploy to standalone/deployments/intranet.war.dodeploy
3. In standalone/deployments/intranet.war folder:
o Edit file WEB-INF/jboss-web.xml - set context-root to /intranet
o Create file WEB-INF/classes/portal-ext.properties and set single property: portal.ctx=/intranet
