[OpenLayers-Users] popups for markers dynamically generated from KML

[Mike Quentel]

I know there is a KML parser and examples that render graphics based on
KML inputs.  Since some of the KML sources I'm using are particularly
huge, instead of having the KML parsed on the client through OL, I have
a server-side KML reader (uses XPath/xalan.jar) that returns lists of
coordinates to the browser client.

So when the client receives a list of point coordinates, it loops
through and adds markers like this: 

for (var i = 0; i < pointsCoordsArray.length; i += 3) {
  x = pointsCoordsArray[i];
  y = pointsCoordsArray[i + 1];
  marker = new OpenLayers.Marker(new OpenLayers.LonLat(x, y),
icon.clone());
  markersLayer.addMarker(marker);          
}

The loop steps by 3 because the point format is lat,lon,altitude.

What I'd like to do is also add a popup for each marker.  I tried
registering a marker mousedown event that would show a popup for
attributes of the marker, but it only shows the attributes for one of
the markers: 

marker.events.register("mousedown", marker, mousedown);

I know many of you have grappled with similar popup problems; I've seen
many posts about popups.  Please, do you have any advice on how to do
this?

Many thanks.
