public class MTAjaxFileUpload
extends com.webobjects.appserver.WOComponent

AjaxFileUpload provides an Ajax wrapper around the file upload process. This works pretty differently than WOFileUpload. The AjaxFileUpload component itself provides its own form and autosubmits when the user selects a file to upload. The upload runs in a hidden iframe, with Ajax updates occurring in the main window. When the final ajax update occurs after the completion of the upload, the appropriate actions fire. This means that if the user navigates away during the upload, no completion/failure/etc notifications will occur.
