OO/Framework, Uploading Images Issue

I am using using a form that uploads a file. If I use a self calling form
that
reinitializes the form values from the bean cfc, my field contatining the
image no longer recognizes it as an image and the
cffile fails.

<cfif isdefined('form.staffid')>
<cfoutput> in isdefined staff </cfoutput>
<cfset staffmember = createobject('component',
'datafoo.cfc.staff').init(form)>
<!--- check for errors before saving --->

<cflock name="photolock" timeout="30">
<cffile action= "upload"
filefield='staffmember.filetoupload'
destination="#expandpath(arguments.directory)##staffmember.filename#"
nameconflict="makeunique">
</cflock
</cfif>

I get the error: The form field staffmember.filetoupload did not contain a
file.


However, if I take that form and instead of recreating the instance from the
bean.init,
just run the upload using the form variable, the image gets uploaded fine

<cfif isdefined('form.staffid')>
<cfoutput> in isdefined staff </cfoutput>
<!--- IGNORE <cfset staffmember = createobject('component',
'datafoo.cfc.staff').init(form)> --->
<!--- check for errors before saving --->

<cflock name="photolock" timeout="30">
<cffile action= "upload"
filefield='file.filetoupload' <!--- *** use form var here -
works --->
destination="#expandpath(arguments.directory)##form.filename#"
nameconflict="makeunique">
</cflock
</cfif>


Any suggestions?
In the bean init I have

<cfcomponent >
<cfproperty name="filetoupload" type="string" default="">

<cfscript>
//Initialize the CFC with the default properties values.
this.filetoupload='';
</cfscript>

<cffunction name="init" output="false" returntype="staff">
<cfargument name="stValues" required="no" type="struct">
<cfif isdefined('arguments.stValues')>
<cfset this.filetoupload = arguments.stValues.filetoupload>
<cfreturn this>
</cffunction>
</component>


Any suggestions?
