Timepicker not reverting to default on page refresh

[philallen1]

I've worked with Timepickers previously and the way I am used to them working is as follows:

I enter the page and the Timepicker is set to a default value (e.g. "Last 24 hours")
I change the Timepicker value (to say, "Last 7 days")
I refresh the page
The Timepicker has reverted to its original value (in this case, "Last 24 hours")

However, when I use a Timepicker on the following XML, it doesn't revert back to its original value, but persists the most recent value:

<module name="TimeRangePicker"  layoutPanel="panel_row2_col1" autoRun="True">
    <param name="selected">last 24 hours</param>
    <module name="HiddenSavedSearch" group="Average 5 Minute Job Time Per Hour" autoRun="True">
        <param name="groupLabel">Average 5 Minute Job Time Per Hour</param>
        <param name="savedSearch">Average 5 Minute Job Time Per Hour</param>
        <module name="ViewstateAdapter">
            <param name="savedSearch">Average 5 Minute Job Time Per Hour</param>
            <module name="HiddenFieldPicker">
                <param name="strictMode">True</param>
                <module name="JobProgressIndicator">
                    <module name="EnablePreview">
                        <param name="display">False</param>
                        <param name="enable">True</param>
                        <module name="HiddenChartFormatter">
                            <module name="JSChart">
                            </module>
                            <module name="ViewRedirectorLink">
                                <param name="viewTarget">flashtimeline</param>
                            </module>
                        </module>
                    </module>
                </module>
            </module>
        </module>
    </module>
</module> 

Anyone have any ideas? It's really frustrating me!

OK I figured this out. The reason why the timepicker date was being persisted was because of the following xml in the top of my code:

isPersistable="true"

I took this out and hey presto, it always reverted to default.
