The value of formatPreference returned from the bean is "html". Here is the
output generated by the tag:
<select name="formatPreference" id="formatPreference"> <option value=""
id="formatPreference_">Select Format Preference</option>
<option value="html" id="formatPreference_html">HTML</option>
<option value="text" id="formatPreference_text">Text</option>
</select>
I see the value of attributes.checkValue is also coming as "html" in
option.cfm.
I did looked at options.cfm and then ended up in option.cfm because I saw
that setAttribute("selected", "selected") is called in there. I will go back
and see if I can find anything else in options.cfm
Thanks,
Sumit
