Package org.springframework.faces.model

Class SelectionTrackingActionListener

java.lang.Object
org.springframework.faces.model.SelectionTrackingActionListener
All Implemented Interfaces:
jakarta.faces.event.ActionListener, jakarta.faces.event.FacesListener, EventListener
public class SelectionTrackingActionListener extends Object implements jakarta.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}
