I'm having trouble refreshing a XUL-template tree once the server-based 
RDF has changed. I've read previous posts on the subject and copied code 
but I can't get a live refresh. When the RDF changes, it takes a browser 
restart to see the changes. I've also futzed with the cache settings, 
but that didn't have an effect.

Here's the code I'm using to refresh:

// ridelist is the templated XUL tree.
var ridelist = document.getElementById("ridelist");
var dsList = ridelist.database.GetDataSources();
var remote = 
dsList.getNext().QueryInterface(Components.interfaces.nsIRDFRemoteDataSource);
if(remote) {
    remote.Refresh(false);
    ridelist.builder.rebuild();
}

Any ideas?

Chuck
