 /**

  * A BeanUtils Converter which delegates to an original convertor or a KEW converter depending on

  * what the current {@link ModuleContext} is.  This allows for the KEW struts module to run inside

  * of an ActionServlet that has the "convertNull" init-param set to null.  The KEW module

  * depends on this being set to true in order for the form processing to work properly.

  * When KEW is embedded in a web application where this is not the case, we need to work

  * around the issue by registering custom converters to convert the values properly when inside

  * the context of the KEW struts module but preserve the conversion behavior of the parent

  * struts module.
