Hi,

I have some polylines that are loaded from xml and get shown/hidden by
checking a checkbox. I put some arrowheads on them to indicate
directon, hoping that the arrows would appear when the line was shown
and dissapear when it was not.

But that's not the case - the arrowheads appear permanently on the
map, regardless of if their relevant line is shown.

Is there some way to bind the arrows to the line, so only the ones
that "belong" to that line get shown when the line does?

Here's my map: http://xelawho.com/map/arrow.htm

the lines get shown/hidden by clicking the Bus Routes boxes down the
bottom.

thanks for your help,

Lucas
