CFFORM bug
I've picked up something weird (and a little bit irritating) with CFFORM in CF 8 and 9.
If you have two fields named x and x_date where x is any name e.g.
data, data_date or
measurement, measurement_date
and field x is cfinput type=text (but you use a number with a decimal)
and field x_date is cfinput type=datefield
then when this form is submitted, field x will be automatically reformatted as a date.
Sample code: create a page called data.cfm and copy this into it.
Click submit and watch variable [data] magically transform into a date.
There is an obvious workaround (just don't name your fields like this) but it took a while to figure this out.

<cfparam name="data" default="1.2">
<cfparam name="data_date" default="#now()#">
<html>
<head>
<title>Untitled Document</title>
</head>
<body>
<cfoutput>
<Cfform name="test" action="data.cfm">
<table>
<tr>
<td>data</td>
<td><cfinput type="text" name="data" value="#data#"></td>
</tr>
<tr>
<td>data_date</td>
<td><cfinput type="datefield" name="data_date" value="#dateformat(data_date,"yyyy/mm/dd")#" mask="dd-mmm-yyyy"></td>
</tr>
</table>
<input type="submit" />
</Cfform>
</cfoutput>
</body>
</html>
