Hi, i'm assigning new playlist to the SWF object. Then it needs to be reloaded it with new param:
sections.change(function(){
var current = $(this).val();
var fextention = ".xml";
//show the loading bar
showLoading();
//reloading player with relevant playlist:
xmlplaylist.val("xml=playlists/"+current+fextention);
var elem = $("#dewplayerpls")[0]; // - #dewplayerpls - is object id
elem.reload();
window.alert( xmlplaylist.val() ); // value correct. reload doesn't happen
}
