public abstract class TilesAction
extends org.apache.struts.action.Action

Base class for Tiles Actions. This class has the same role as Struts Action. It provides a method execute(...) called when action is invoked. The difference is that the execute() method takes an additional parameter : tile context. This class extends Struts Action. Subclasses should override execute(ComponentContext ...) method instead of Struts execute(ActionMapping ...) method. Backward compatibility is ensure with the perform(ComponentContext ...) method.
