You can find the following sample code for defining a portlet as extension point in the CentraSiteBUIExtension.gwt.xml file that is provided in the demos folder under the CentraSite installation folder.

Important: | On a custom portlet defined as GWT extension point, whenever you execute a basic action (for example, Expand, Collapse, or Close) through the user interface, CentraSite internally sends a corresponding actionId to the GWT extension. |
