Hi.
I am using a combination of Fixed and Refresh strategies, to always get all
data from a GeoJSON datasource and refresh the layer every 10 seconds. This
works in FF, but in IE no update occurs. The first getting of data worked
somehow, but it never updates. From what I can ses, the refresh() function
triggers in OpenLayers.Strategy.Refresh, but there is no request issued to my
backend. Is there a known issue with caching of these requests in IE, or is it
something else? Any pointers are welcome.
My layer definition looks like this:
var layer = new OpenLayers.Layer.Vector("Mobile", {
strategies: [
new OpenLayers.Strategy.Fixed(),
new OpenLayers.Strategy.Refresh(
{
interval: 10000,
force: true
}
)
],
protocol: new OpenLayers.Protocol.HTTP({
url: "/Location/Locations.ashx?output=geojson",
format: new OpenLayers.Format.GeoJSON(
{
'internalProjection': new
OpenLayers.Projection("EPSG:3006"),
'externalProjection': new OpenLayers.Projection("EPSG:4326")
}
)
})
,
styleMap: new teratools.map.styleMap.mobileLocations()
});
Thanks in advance.
- Niklas
