All Implemented Interfaces:

java.io.Serializable

public class NoRequiredParamException

extends javax.servlet.ServletException

This exception is thrown by the ShowPageAction when it can't find a required presentation element input parameter in the scope while setting it up. The reason it is a separate exception type is that you can filter it with an onerror element of a page descriptor and forward to some special page instead of throwing the exception further to the servlet container.
