Subject [jira] [Created] (CB-1593) WP7 : Media callback called multiple times
Date Fri, 05 Oct 2012 14:10:02 GMT
Christophe A. Guilmart created CB-1593:
------------------------------------------

             Summary: WP7 : Media callback called multiple times
                 Key: CB-1593
                 URL: https://issues.apache.org/jira/browse/CB-1593
             Project: Apache Cordova
          Issue Type: Bug
          Components: WP7
    Affects Versions: 2.1.0
         Environment: Nokia Lumia 800 with WP 7.5 (7.10.8773.98).
            Reporter: Christophe A. Guilmart
            Assignee: Jesse MacFadyen
            Priority: Critical


When using this code

          function play(){
            cordovaMedia = new Media("app/www/test.mp3", onSuccess, onError, onStatus);
            cordovaMedia.play();
		  }

		  
I encounter the following problems:

* 1st call to play() does not work (ie: I don't hear the sound). nor are the callback called.
* following play work, but callback are called multiple times.
* onError is called even when play sound is successful (ie: when I can hear the sound).
* if onStatus callback is not provided, an error show up in the log.

Expected behavior:
* onError & onSuccess should be exclusive. One OR the other should be called. Not both.
* onError & onSuccess should be called only once per call to .play()
