public void processRequest(OAPageContext paramOAPageContext, OAWebBean paramOAWebBean)

{

   super.processRequest(paramOAPageContext, paramOAWebBean);

  

}

  

public void processFormRequest(OAPageContext paramOAPageContext, OAWebBean paramOAWebBean)

{

  

     DocumentAMImpl localDocumentAMImpl = (DocumentAMImpl)paramOAPageContext.getApplicationModule(paramOAWebBean);

           //OAViewObject localOAViewObject1 = (OAViewObject)localDocumentAMImpl.findViewObject("PoHeaderMergeVO");
