requestContext.launchDialog parameters

[Eisenträger , Tobias]

Hello Community,

I am trying to launch an error dialog programmatically, but the arguments of  
requestContext.launchDialog won't work - did something change here? I was 
following the tutorial on 
http://myfaces.apache.org/trinidad/devguide/dialogs.html#Manually%20Launching%20A%20Dialog
 but instead of null for the parameter I would like to provide the exception.

public void launchErrorDialog(Exception pException) {
      FacesContext ctx = FacesContext.getCurrentInstance();
      ViewHandler viewHandler = ctx.getApplication().getViewHandler();
      
      UIViewRoot dialog  = viewHandler.createView(ctx, "/error.jspx");
      
      Map windowProperties = new HashMap();
      windowProperties.put("width", new Integer(300));
      windowProperties.put("height", new Integer(200));
      
      Map dialogParameters = new HashMap();
      dialogParameters.put("exception", pException);
      
      RequestContext requestContext = RequestContext.getCurrentInstance();
      
      requestContext.launchDialog(dialog,
            null, // not launched from any component
            dialogParameters, // dialog parameters - this doesn't work! - it 
expects UIComponent here, but on the tutorial it expects a map.
            true, // show it in a dialog
            windowProperties // width and height
            );
   }

Thanks!
