I'm trying to display a different base layer, depending on zoom levels. I use
the following code:
map.events.register("zoomend", map, function() {
if (map.getZoom()>0) {
if (map.getNumLayers()<5) {
map.addLayers([satellite, hybrid]);
//map.setBaseLayer(satellite]);
map.removeLayer(nomoi);
}
}
else
{
map.removeLayer(satellite);
map.removeLayer(hybrid);
map.addLayer(nomoi);
}
});
the above works well when you zoom in and out the map, but if you get to the
extents of the map (zoomlevel:0) when else code executes, then if you try to
zoom again in the map, the code stops working and I see in Firefly that the
problem is:
this.pane has no properties
[Break on this error] this.pane.style.zIndex =
parseInt(this.div.style.zIndex) + 1;
moreover when I try changing the baseLayer as well with
//map.setBaseLayer(satellite]);
this works but the whole behavior of layer switcher is altered. I can't no
longer switch between different baselayers from layer switcher. when i click
on a layer, the whole map pans
help please!
