Class SelectionTrackingActionListener

java.lang.Object
  org.springframework.faces.model.SelectionTrackingActionListener

All Implemented Interfaces:

java.util.EventListener, javax.faces.event.ActionListener, javax.faces.event.FacesListener

public class SelectionTrackingActionListener
extends java.lang.Object
implements javax.faces.event.ActionListener

Custom ActionListener that inspects the UIComponent that signaled the current ActionEvent to determine whether it is a child of any iterator type of component (such as UIData) that uses a SelectionAware data model implementation. If a containing SelectionAware model is found, the row containing the event-signaling component instance will be selected. This enables convenient access to the selected model state at any time through EL expressions such as #{model.selectedRow.id} without having to rely on the whether or not the current row index is pointing to the desired row as it would need to be to use an expression such as #{model.rowData.id}
