public abstract class TilesAction

extends 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 ensured with the perform(ComponentContext ...) method.
