Can you catch form has expired exception and reload page?

Question

I have a cfcalendar wrapped with cfform, every first time start the application, it either is empty or give me form data as expired message.
I have tried to set cfform timeout to a 100 or 200 seconds, but if you close the application and next time open it (if after the timeout limits) it shows the form data has expired message again. If I don't set or set it to 0, then the next time I open the browser, it give me an empty form page.
So I wonder if there is a way to catch that exception, and then make it reload the page?
Any ideals to solve the problem.
<cfoutput>
<cfheader name="expires" value="#now()#">
<cfheader name="pragma" value="no-cache">
<cfheader name="cache-control" value="no-cache, no-store, must-revalidate">
</cfoutput>
<cfform name="testForm" format="flash" onLoad="#disableRanges#" height="320" width="420"   >
     <cfcalendar name="selectedDate" 
            selecteddate="#Form.selectdate#"
            mask="mmm dd, yyyy"
            dayNames="SU,MO,TU,WE,TH,FR,SA"
            monthNames="JAN, FEB, MAR, APR, MAY, JUN, JUL, AUG, SEP, OCT, NOV, DEC"
            style="rollOverColor:##FF0000;"
            width="270" height="200"
            onchange="getURL('index.cfm?selectDate=' + (selectedDate.selectedDate.getMonth()+1) + '/' +selectedDate.selectedDate.getDate() + '/' + selectedDate.selectedDate.getFullYear());"
                 >
</cfform>   
Thanks,

The first thing I would do would be to use an html form instead of flash.  The second would be to add a submit button.  On change events are very frustrating if you don't make the correct selection on your first attempt.
