[Google Maps API v3] Stuck with making a saved polyline editable again?

[123gotoandplay]

Hi,

I am bit stuck with making a saved polyline editable again. At the moment i 
have stored the points in a mysql database and i am able to show the 
route/polyline again with custom markers.

Now i like the polyline to be editable again and for this i was looking 
into:
http://www.birdtheme.org/useful/v3tool.html

Issues i have:
1/ i can't get the already saved points to be drag and drop
2/ i don't want the midmarkers, just the ability to move markers, add and 
delete markers

At the moment my startediting function looks like:

function startEditing(){
               
                if(editing === true){
                        stopediting();
                }else{
                routeCoords = theRoute.getPath();    
                //remove custom icons
                //setAllMap(null);
                if(routeCoords.length > 0){
                           for(var i = 0; i < routeCoords.length; i++) {
                                var marker = 
setmarkers(routeCoords.getAt(i));
                               //alert("marker: "+marker);
                               markers.push(marker);
                               if(i > 0) {
                                   var midmarker = 
setmidmarkers(routeCoords.getAt(i));
                                   midmarkers.push(midmarker);
                               }
                           }
                           editing = true;
                           jQuery('#btnEditing').removeClass('green');
                           jQuery('#btnEditing').val('Stop 
Editing').addClass('red');
                       }
                        
                }
        }

and function setmarkers looks like
function setmarkers(point){
             var marker = new google.maps.Marker({
                position: point,
                map: map,
                icon: imageNormal,
                raiseOnDrag: false,
                draggable: true
            });
            google.maps.event.addListener(marker, "mouseover", function() {
                marker.setIcon(imageHover);
            });
            google.maps.event.addListener(marker, "mouseout", function() {
                marker.setIcon(imageNormal);
            });
            google.maps.event.addListener(marker, "drag", function() {
                
                for (var i = 0; i < markers.length; i++) {
                    if (markers[i] === marker) {
                        theRoute.getPath().setAt(i, marker.getPosition());
                        movemidmarker(i);
                        //movemarker(i);
                        break;
                    }
                }
                routeCoords = theRoute.getPath();
                var stringtobesaved = marker.getPosition().lat().toFixed(6) 
+ ',' + marker.getPosition().lng().toFixed(6);
                pointsArray.splice(i,1,stringtobesaved);
            });
                      
           ////#end markers van DB
           
            google.maps.event.addListener(marker, "click", function() {
                alert("lengte "+length);
                for (var i = 0; i < markers.length; i++) {
                    if (markers[i] === marker && markers.length !== 1) {
                        marker.setMap(null);
                        markers.splice(i, 1);
                        theRoute.getPath().removeAt(i);
                        removemidmarker(i);
                        break;
                    }
                }
                routeCoords = theRoute.getPath();
                if(markers.length > 0) {
                    pointsArray.splice(i,1);
                    
                }
            });
            
            
            return marker;

        }


Any suggestions?
