Ym4r user - Jul 2007 - layers of polylines, events building up on map

Hi all,

Here''s my situation:

I have a little route creation app that lets a user create a route.

I''m using the mapstraction version of ym4r...

here is the workflow:

first page has a map displaying the start point of existing routes.

if they click "new route:
creates a route_object
clears all polylines in case there are any
clears all the markers and adds an onclick event.

for each click I:
    clear all polylines with RJS
    add point to the waypoint table (with route_id)
    select all waypoints for the route and build a polyline
    display the polyline

that all works fine....

but if I hit the create route button again
as I click the polylines from the last route flash and then go away
also it seems that my onclick events are multiplying as well (2 clicks 
are registered when I click once)

and if I hit new route again it becomes 3, etc.

Any ideas on how to clear out my events and polygons completely when I 
create a new route?

Thanks for the help!

Chuck
