I am de-constructing a very old and convoluted ColdFusion application.
*One*
-----
I have a page with this url:
http://calpip-devsite/county.cfm
*Two*
-----
On this page, through a mind boggling series of logic branches and
include files there is this bit of code for a form.
<form action="" name="NavForm" method="post" style="" target="_top">
<select class="bluelink" name="ds" style="position: relative; left:
12px; font-size: 70%;" onchange="document.forms.NavForm.submit()">
<option value="PUR" onclick="document.NavForm.submit()"
title="Pesticide Use Report">PUR</option>
<option value="GWPA" onclick="document.NavForm.submit()"
title="Ground Water Protection Area">GWPA</option>
<option value="PRESCRIBE" onclick="document.NavForm.submit()"
title="Endangered Species Bulletin"
selected="selected">PRESCRIBE</option>
</select>
</form>
*Three*
-----
When I select an option in that form, I can see that the browser is
re-requesting the county.cfm template.

I have modified the county.cfm page so that line 1 is a dump of the
session and form structures.
<cfdump var="#session#"><cfdump var="#form#" label="AppFlow.cfm"><cfabort>
*Conclusion*
-----
Can anybody provide any insight on how selecting a value in the above
form will change the value of the "ds" key in the session structure
without any visible action code?
I am flabbergasted and astonished. I have never seen behavior like this.
