This sample shows you how to use IBM® WebSphere® Portlet Factory to implement inter-portlet communication using the property broker. More specifically, the sample shows how to chain portlets together. This means that a value is passed from the source to a target. The target portlet then passes the value on to another portlet or to the source portlet. In the attached example, the value is passed from source to target and back to source again.
