This statement helps a ton!
I now have a little function that can reload the data in my exhibit.
Looks like this:
function reloader () {
Exhibit.UI.showBusyIndicator();
window.database.removeAllStatements();
var importer = Exhibit.importers["application/json"];
importer.load("GetActiveCalls.aspx", window.database,
function () {Exhibit.UI.hideBusyIndicator();});
}
It reloads the data great! The only issue right now is that the
showBusyIndicator does not seem to be working. I see the exhibit go
blank - a good pause and then the new data shows up. It would be nice
to show the busy thing during that pause. Am I missing something?

I just added a method for clearing the data
window.database.removeAllStatements();
Let me know if that helps.
