passing form to cfc using javascript and cfajaxproxy

Hello,

environment: cf8 (win); no db;

I'm trying to pass the form scoped refernce to a method that uses cffile to upload a file. My understanding with cffile is that the form field needs to be passed to the method as scoped as a form struct in order to get the file to upload (otherwise i get a enctype error). Is it possible to pass the form through the javascript object reference to the cfc? (serializing the form doesn't seem to work)

sample code;

<cfajaxproxy cfc="name" jsclassname="jsNews" />

...

<script>

function fnSetNews(id){

var cfc = new jsNews();

file=$('#file_'+id).val();---not quite sure how to call;  I would prefer to keep the script on a .js file (no fancy cf referencing)

var response=cfc.setImage(file);

/*file is a valid form path selected on a "file" field of a form.*/

}

</script>

...

<form id="unique" class="frmUpload">

<input type="file" name="unique" id="unique" />

<input type="submit" value="go" />

</form>

...

listener (calls the js function upon submit)

$('.frmUpload').livequery('submit',function(event){fnSetNews(this.id);return false;});

...

cfc code:

<cffunction name="setImage" access="package" output="true" returntype="Any">

<cfargument name="fileField">

<cffile action="upload" filefield="#ARGUMENTS.fileField#" destination="validPath" nameconflict="overwrite">

</cffunction>

any help is greatly appreciated-dj
