Form fields are available via get(Object) without calling this method. Uploaded files still need to be processed via the passed callback function.

This callback function is called for each file upload part in the request. The parameters are the field name, the content type and the original file name. The function can return either a null, which means that the upload of this part should be skipped, or return a dw.io.File instance. If the file is an existing directory the system will automatically generate a unique file name. If the file is not an existing directory the uploaded content will be directly stored into that file. An existing file with the same name will be deleted. If the file can't be deleted for whatever reason, the upload is stored with a generated unique file name in the indicated directory.

An automatically generated file name consists of the the prefix "upload", a time stamp, a unique id and the extension tmp. For example: "upload_20070114221535_bc7H1aOadI9qYaaacovPd3lqna.tmp".

 var params : HttpParameterMap = pdict.CurrentHttpParameterMap;

 // Get the file name from the first field. This is works because the
 // parameter map is updated before the file part is parsed.
 var files : LinkedHashMap = params.processMultipart( (function( field, ct, oname ){
     return new File( File.IMPEX + "/" + params.firstField );
 }) );
