Google Map expert

please read carefully job description. I have a Google Map on which the user can draw. After this, the user can save it on the server. It works fine But the big problem is, after reloading the lat/lng from the server and drawing it on the map, the event listener does not know about the new polygon: But the user can change the polygon and want to save the new changed polygon on the server. The listener: [login to view URL](drawingManager, 'polygoncomplete', function (polygon) Does not recognize that the polygon has been drawn. And therefore the listener doesn't recognize when the user changes the polygon. The question: How can I send the automatically drawn polygon coordinates to the "map" object? Alternatively, how can I fire an event to "polygoncomplete", so it will recognize the new polygon? The other idea I had: Trigger a mouse click event at the map with the coordinates, so the listener must recognize that the map has changed. But unfortunately this didn't work. Has anybody any idea how to solve this issue?
