Hello.

I dunno whether it is a real bug or not, but here's the situation.

Assume that I define an object like so:

var postObject = { "varInt": 133, "varString": "foo" };

It is pretty fair. Then I create, let's say, a DIV and attach some data to it:

var modalDiv = $("<div></div>").data("aCallback", { "invoker": invoker, "id": id });

I create a jQuery UI dialog then with this modalDiv a common way (I also load its content, buttons and handlers via AJAX). Then I hit one of the button which means, let's say, "to add data". This invokes handler that execute some jQuery processing code including this:

postObject['aCallback'] = modalDiv.data("aCallback");

And, finally, performs one more AJAX request like so:

$.post("processRequest.php", postObject, function(data){

//some feedback here

});

And at this point all process fails silently. Using Firebug I've found out that such behavior is because of adding this 'data' to my postObject! If I don't do such a thing - all goes well!
