Shawn, The demos look *very* impressive so I thought I'd give it a try. I've several places in my current project where I upload files, but my progress bar solution does not work so well with IE (as in 15%, loooong wait, Done!). I'm quickly hitting an exception with Uploader. Maybe you have some insight. I use UiBinder throughout. Since Uploader doesn't have UiBinder tags, I thought I could put in a SimplePanel then assign Uploader to it. In my FooViewImpl.ui.xml I add: <g:HTMLPanel'> <div> <g:Label ui:field='progress'></g:Label> <g:SimplePanel ui:field='uploadRaw'></g:SimplePanel> </div> ... In FooViewImpl.java I add @UiField Label progress; @UiField SimplePanel uploadRaw; public FooViewImpl() { initWidget(uiBinder.createAndBindUi(this)); // uploader JSONObject params = new JSONObject(); params.put("fileType", new JSONString("raw text")); Uploader uploader = new Uploader() .setUploadURL(GWT.getModuleBaseURL()+"/uploadInput") .setButtonText("Upload") .setPostParams(params); uploader.setUploadProgressHandler(new UploadProgressHandler() { @Override public boolean onUploadProgress(UploadProgressEvent evt) { progress.setText(NumberFormat.getPercentFormat().format( evt.getBytesComplete() / evt.getBytesTotal())); return true; } }); uploadRaw.setWidget(uploader); This is pretty much the quick start at http://www.moxiegroup.com/moxieapps/gwt-uploader/quickstart.jsp but allowing for UiBinder. When I click the "Upload" in the UI, I get the error below. I don't see Uploader in the stack trace to I dunno where to start. Thanks.
