[jboss-dev-forums] [Design of JBoss Portal] - An error occured while rendering window 'default.Admin.Manag

[jaimegonza]

Hello,
I am using Jboss-portal.2.4.1 and when I enter the part of administration portlet 'default.Admin.ManagementPortletWindow' it gives the following error:

/WEB-INF/jsp/management/index.xhtml @41,58 rendered="#{!empty node.children}": org.jboss.portal.core.portlet.management.LazyPortalObjectTreeNode


Somebody can say to me what is failing and like solving it? 

Thank you very much anticipated. 

Warm greetings.
