extends TilesUtilStrutsImpl

Implementation of TilesUtil for Struts multi modules. Methods in this implementation are aware of the Struts module context.

• Methods doForward() and doInclude() use their counterparts in the current RequestProcessor (todo).
• The method createFactory(...) creates a factory for the current module and stores it under the appropriate property name.
