Ryan,
I modified the reuseForm tag to work around missing values from form input and from
queries. If the form/Query value is not defined, it puts in the default value
specified in your formfields parameter (or an empty string). Works great.
Here's the part of the tag that does the action=form part:
<cfcase value="form">
<CFLOOP LIST="#attributes.fieldlist#" INDEX="counter">
<CFSET fldName = listgetat(counter,1,";")>
<CFIF IsDefined("form.#fldName#")>
<CFSET "caller.#fldName#" = evaluate("FORM." & fldName)>
<CFELSE>
<CFIF ListLen(counter,";") gt 1>
<CFSET defaultvalue=ListGetAt(counter,2,";")>
<CFELSE>
<CFSET defaultvalue="">
</CFIF>
<CFSET "caller.#fldName#" = defaultvalue>
</CFIF>
</CFLOOP>
</cfcase>
Same idea for queries.
HTH,
