Store.remove using LocalStorage proxy not working for me

[JacobGu]

My app periodically refreshes a data store of employee records using a LocalStorage proxy. Each refresh, if I call the remove method on entire record range, it does not remove the records (at least synchronously), and then will cause records to be duplicated each refresh (1x, 2x, 3x, 4x, etc.). What I did as a workaround was access localStorage object directly to remove the data and then reload store from localStorage.

This is a code excerpt:

TC.DeleteLocalStorageThatBeginsWith('tcEmployeeCache');
//TC.employeeCache.remove(TC.employeeCache.getRange()); // not removing records for some reason
TC.employeeCache.load();
TC.employeeCache.add(pingResult.employees);
TC.employeeCache.sync();            

TC.DeleteLocalStorageThatBeginsWith = function(keyPrefix){
	var len = localStorage.length;
	// reverse iterate collection to allow inline removal
	for(var i = len-1; i >= 0; i--){
		var key = localStorage.key(i);
		if(key.indexOf(keyPrefix) == 0){
			localStorage.removeItem(key);
		}
	}
}

Is this an issue of asynchronous removal? What is the correct way to do this within Sencha API?

Thanks.

You are absolutely correct! Adding an id fixed the problem. Looks like a Sencha bug, either in code or in documentation of the 'id' field.
