Can't fire events to separate grids from filter

[J]

OK in short, I have one grid that, based on row selection, populates another grid. I would like filtering on the first grid to "reset"/"clear" the second grid, and obviously filter the first grid. The problem I'm seeing is that only one event will fire - if I make the filter happen first, the filter works but the .fireCommand() event doesn't fire. If I make the .fireCommand() event first, the event is fired but the filter doesn't happen. Code for the filter function below.

 

function NameChanged(sender) {
    var firstGrid = $find("<%= rgUsers.ClientID %>").get_masterTableView();
    var secondGrid = $find("<%= rgAccess.ClientID %>").get_masterTableView();

    if (sender.get_value() == "") {
        tableView.filter("gbcFullName", sender.get_value(), "NoFilter");
    }
    else {
        tableView.filter("gbcFullName", sender.get_value(), "Contains");
    }

    secondGrid.fireCommand("Clear", "");
}

Anyone? Anyone have alternative solutions if this is a bug?
