public abstract class KualiAction
extends org.apache.struts.actions.DispatchAction

The base Action class for all KNS-based Actions. Extends from the standard DispatchAction which allows for a methodToCall request parameter to be used to indicate which method to invoke.

This Action overrides #execute to set methodToCall for image submits. Also performs other setup required for KNS framework calls.
