[flexcoders] Processing Filedata / Filereference with a CFC instead of CFM?

[qnotemedia]

I'm using a component from eFlex, called Uploader.  Has anyone else 
run into this?  Its really quite brilliant and was a breeze to 
implement and customize for my own needs:

Go here: http://www.everythingflex.com/
and search for "Uploader."

But, from what I understand, the cfm processing for this, is the same 
as any other methodology when using Flex and Coldfusion for uploading 
data.  The CFM I have that works, is a single line:

<cffile action="upload" filefield="Filedata" destination="#ExpandPath
('./logos')#" nameconflict="OVERWRITE">

Can someone show me an example of this when used with a CFC instead 
of a CFM?  I want to do some checks and balances in ColdFusion before 
physically using the cffile, and if those checks don't validate, 
return an error message to Flex.  Is that possible?  In fact, one 
problem with this component is when an upload error occurs, no 
message is sent to the user.

What follows is the getFile() function found in the Uploader mxml.

Thanks,

public function getFile():void {
  if(this.uploadToURL.length > 0){
    this.uploadURL = new URLRequest();
    this.uploadURL.url = this.uploadToURL;
    /* uploadURL.url is defined per component instance and leads to 
the CFM for processing */
    this.file = new FileReference();
    this.configureListeners(file);
    this.file.browse(new Array(new FileFilter("Images", 
this.imagesFilter)));
  } else {
    Alert.show("uploadToURL is undefined", "Syntax Error");
  }
}
