Hey Martin,
I get now a CastException in:
Root cause:
java.lang.ClassCastException:
org.apache.wicket.response.StringResponse cannot be cast to
org.apache.wicket.request.http.WebResponse
at
org.apache.wicket.request.handler.render.WebPageRenderer.redirectTo(WebPageRenderer.java:134)
at
org.apache.wicket.request.handler.render.WebPageRenderer.respond(WebPageRenderer.java:214)
at
com.freiheit.tango.presentation.application.WicketUtils.renderPageNew(WicketUtils.java:54)
the corresponing line is:
final WebApplication application = WebApplication.get();
final RenderPageRequestHandler handler = new
RenderPageRequestHandler(new PageProvider(pageClass, pageParameters));
final PageRenderer pageRenderer =
application.getPageRendererProvider().get(handler);
final Response oldResponse = requestCycle.getResponse();
final StringResponse newResponse = new StringResponse();
requestCycle.setResponse(newResponse);
--> pageRenderer.respond(requestCycle); <---
requestCycle.setResponse(oldResponse);
return newResponse.toString();
But seems to get closer ;-)
I can add the ticket when my case is running.
Greetings
Stefan
