I recently added both a FlexSpaces/Alfresco Gadget (Google) and a Portlet for the new GateIn (eXo+JBoss) Portal. See Alfresco Forge for downloads, Google Code for source. See previous posts on other portlets ( Liferay Portal portlet , JBoss Portal portlet).
The gadget and the portlet work on both app server versions (Tomcat, JBoss AS) of the GateIn beta1. (I had to add a tld file to get the portlet to work on JBoss).
The gadget can be used on dashboard layouts. The portlet can be used in other layouts. In the screenshot, the FlexSpaces gadget is maximized, so it doesn’t look like the usual gadget layout. The beta1 seemed to not allow saving an edit to change from a 3 column to a 1 or 2 column. (FlexSpaces can made to take up less space by setting the show header area preference to false, and hiding the tree with the show / tree menu). Also the beta1 didn’t display default values for the FlexSpaces gadget when the edit UI mode is used, so editng the gadget xml is easier (This is only on gadgets, regular portet preferences UI edit mode was fine).
See the readmes in the flexspaces-gadget.zip file and the flexspacesGateInPortlet.zip file for setup instructions.
