You can find sample code for defining the custom portlet as an extension point in the file CentraSiteBUIExtension.gwt.xml. You can find the file in the demos folder in the <CentraSiteInstall_Directory>.

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