push notifications with param don't receive windows phone

Question

I've come across a very strange problem. I've implemented push notifications inside my application and it works fine, but only If I don't send a param with the push notification. My application is a Windows Phone 8 Application.

For some reason the push notifications with the param won't arrive on my phone, but without the param they do. I've tried a lot if "inputs" to check if it was because it wasn't a valid uri, string, etc, but nothing happens.

Even stranger is that the response from the Microsoft server says that it is delivered.

HTTP/1.1 200 OK Cache-Control: private Server: Microsoft-IIS/7.5 X-DeviceConnectionStatus: Connected X-NotificationStatus: Received X-SubscriptionStatus: Active X-MessageID: 00000000-0000-0000-0000-000000000000 ActivityId: 381e48cc-7a1d-4076-979d-953a622bfc7d X-Server: DB3MPNSM009 X-AspNet-Version: 4.0.30319 X-Powered-By: ASP.NET Date: Fri, 06 Sep 2013 19:17:32 GMT Content-Length: 0

                </wp:Notification>

Send and receiving

                        <wp:Param></wp:Param> 
                   </wp:Toast>
                </wp:Notification>

I've have no clue any more what the problem could be. I hope someone can help me out.

Answer 1

The answer could be in here http://msdn.microsoft.com/en-us/library/windows/apps/jj662938(v=vs.105).aspx... I had the same issue when I was using multiple query string parameters.

I did ?something=value&somethingelse=value (failing) Then I noticed the & was encoded using & in the example.

So when I changed it to ?something=value&somethingelse=value, the notification was successfully received.
