Description

As discussed on the mailing list on 11/29/2011 in "Redering to to file in wicket1.5" we dicussed to get the rendered page in a String. My running Example looks like that:

/**

• Renders a Page and returns it.
  *
• known issue: In my experience you cannot call it in a constructor of a page.
  */
  public static String renderPageToString(
  final RequestCycle requestCycle,
  final Class<? extends Page> pageClass,
  final PageParameters pageParameters) { final WebApplication application = WebApplication.get(); final RenderPageRequestHandler handler = new RenderPageRequestHandler( new PageProvider(pageClass, pageParameters), RedirectPolicy.NEVER_REDIRECT); final PageRenderer pageRenderer = application.getPageRendererProvider().get(handler); final Response oldResponse = requestCycle.getResponse(); // final StringResponse newResponse = new StringResponse(); final MockWebResponse mockWebResponse = new MockWebResponse(); requestCycle.setResponse(mockWebResponse); pageRenderer.respond(requestCycle); requestCycle.setResponse(oldResponse); return mockWebResponse.getTextResponse().toString(); }
