Problem with Virtual Earth GeoRSS

[GunnarJ]

I am using a VE map in an asp.net application to allow users to display data that they can filter through selecting rows in dropdownboxes. When they have set the filters I create a GeoRSS-file and import it into the map with

map.ImportShapeLayerData(veLayerSpec, onFeedLoad,true );

veLayerSpec points to the GeoRSS-file.

My problem is that it works OK the first time but when I do a new selection and create the GeoRSS-file, I can verify that it contains the new data but when I click the import-button it continues to show the previous result. I have traced the javascript function and it obviously works but somehow gets the old data in.
Is there som kind of caching happening here or is there another answer?

I have tested with a button that deletes all layers on the map and then reload the new GeoRSS-file but the old contents shows up again even though I have opended and verified that the file itself conains new data

Btw the dropdownboxes and buttons are inside a update-panel to minimize postbacks.

It probably is a caching problem. Can you show the JavaScript code?
