I think I figured out the mistake. The array index variable I was
trying to use in javascript is actually defined in JSP. So the
variable reference was failing. I changed my code to:
poly[<%out.println (b);%>] = new GPolyline([...
It worked fine. I can now add and remove polylines. I would however be
interested in knowing, if there is a better way to add and remove
multiple polylines. I need multiple polylines so that I can give them
different colors.
