Does someone knows how to enable the Ajax Loading Mask Layer in the gatein navigation portlet?
FYI, this feature does not work if you are using the GateIn 3.1.0-GA and It is addressed by https://jira.jboss.org/browse/GTNPORTAL-1381
Normally to make it work, you just need to configure the "useAJAX" preference to true for the navigation portlet
