Draggable doesn't use jQuery context.

If we have the situation mentioned here.

http://stackoverflow.com/questions/539504/run-jquery-in-the-context-of-another-frame

Where the frameset contains jQuery UI code and the draggable element is inside a frame. The Draggable code will bind the mouse to the frameset document, NOT the frame.

Ideally, if this is passed in.

$(panel, childFrame.document).draggable();

The mouse bindings should be done to the childFrame.document, not the frameset's document.

These are the lines that could be changed to use jQuery context.

$(document)

.bind('mousemove.'+this.widgetName, this._mouseMoveDelegate)

.bind('mouseup.'+this.widgetName, this._mouseUpDelegate);

and

$(document)

.unbind('mousemove.'+this.widgetName, this._mouseMoveDelegate)

.unbind('mouseup.'+this.widgetName, this._mouseUpDelegate);

$(document) should refer to the context passed in.
