DayPilot.request broken after update

This happens because the "args" object has been extended with new properties (including a reference to DayPilot.Scheduler instance) and it can't be serialized using JSON.stringify() anymore.

It's necessary to replace the "args" object in DayPilot.request calls with a custom object that selects the required properties, e.g.

dp.onEventMoved = function (args) {
    var params = { id: args.e.id(), newStart: args.newStart, newEnd: args.newEnd, newResource: args.newResource };
    DayPilot.request(
        "backend_move.php", 
        function(req) { // success
            var response = eval("(" + req.responseText + ")");
            if (response && response.result) {
                dp.message("Moved: " + response.message);
            }
        },
        params,  // used to be args
        function(req) {  // error
            dp.message("Saving failed");
        }
    );        
};

Thank you for the quick reply.
That solved the problem :-)
