On specific use case trying to read "source" property of instance of mdm.MediaPlayer would result in application crash.

To repeat please compile provided example.

The issue only occurs if:
- instance of mdm.MediaPlayer was created with empty path passed in constructor
- the "source" property has been set on such instance on later code call
- the "source" property was tried to be read via call,
that is as in example below:

function initApp():void
{
debug("initApp();");
// create instance of player with empty path (allowed)
mediaPlayer = new mdm.MediaPlayer(0, 0, stage.stageWidth, stage.stageHeight/2, "none", false, true, "");
mediaPlayer.onWMPChangeState = playerNewState;
// now after player is craeted with empty path
// set new path using that property
// if we pass a path in constructor - no subsequent crash occur
// on "property" read operation
var path:String = mdm.Application.path+"sampleOne.wmv";
mediaPlayer.source = path;
};
/**
* called by media player instance when
* player state is changed
* when playback is 3 (playing) for the first time try to read "source" property of player
*/
function playerNewState(evt:Object):void
{
debug("player newState: "+evt.newState);
// 3 (Playing)
if(evt.newState == "3")
{
// try to show what is played in player
debug("now playing: "+mediaPlayer.source);
};
};
