Validation turned off - still getting a validation message

Question

CF9 (NOT CF901), no hotfixes, no updates, no patches.
CFFORM with name and ID parameters, nothing else.
Form contains two text fields (both are used for date in MM/DD/YYYY format),
     six checkboxes (all unique name/id), two radio (both same name/id), and a submit button.
The text fields, checkboxes, and radio are all <INPUT>, the submit is <CFINPUT>.
NONE of the names/ids contain underscore or hyphen or anything other than
     alpha characters (not even numbers.)
Regardless of whether the "Start Date" is 1/1/2011 or 01/01/2011, when the submit
     button is clicked, an alert box will display "Invalid Start Date Format. Use MM/DD/YYYY",
     and the form will submit, anyway.
There is not any JavaScript validation; there are no parameters or settings asking CF to validate.
Has anyone else run across this "ghost" validation error?
Thanks,
^_^

The action and method have been added by another developer since I made my original post.
Same for the CFSELECT.
<cfform id="reportFilters" action="reportContent.cfm" method="post" >
<table id="filter-selection">
<tr>
<td><input type="radio" name = "level" value="directReports"   checked/>
Direct Reports</td>
<td><input type="radio" name = "level" value="wholeOrg"  />
Whole Organization</td>
<td><input type="checkbox" id="management" name="management" checked="checked" />
<label for="management">Management</label></td>
<td><input type="checkbox" id="nonManagement" name="nonManagement" checked="checked" />
<label for="nonManagement">Non-Management</label></td>
<td>*These filters apply to all sections</td>
