[OpenLayers-Users] redraw or refresh a text layer?

[Carl Morgan]

Regina,

I got the following function to redraw the layer. Not sure I understand 
why this works, but it does. I call it immediately after I call my init 
function. I appreciate your help!

        function refresh_markers() {

            reports.redraw(true);
            map.removeLayer(reports);
            reports.destroy();
            reports = new OpenLayers.Layer.Text( "New Rep", {location: 
"./" + textfile + "?" + Math.random()});
            map.addLayer(reports);
        }
