[OpenLayers-Users] Any idea of using setUrl on GeoRSS layer?

[Eric Lemoine]

Hi. You use a GeoRSS layer and look at the code of the Layer.Image class!

Layer.GeoRSS does not have a setURL method. You can try something like
this in your setInterval callback:

layer.clearFeatures();
layer.loaded = false;
layer.loadRSS();

Hope this helps,

Eric
