Class UpdateActionListenerTag

java.lang.Object
  javax.servlet.jsp.tagext.TagSupport
      org.apache.myfaces.custom.updateactionlistener.UpdateActionListenerTag

All Implemented Interfaces:

java.io.Serializable, javax.servlet.jsp.tagext.IterationTag, javax.servlet.jsp.tagext.JspTag, javax.servlet.jsp.tagext.Tag

public class UpdateActionListenerTag
extends javax.servlet.jsp.tagext.TagSupport

Registers an org.apache.myfaces.custom.updateactionlistener.UpdateActionListener at the parent component (which must be an ActionSource). When the parent's action fires the specified value is evaluated, then written into the specified property. Unless otherwise specified, all attributes accept static values or EL expressions. JSF 1.2 introduces a "setPropertyActionListener" with the same functionality like this.
