SubmitCompleteEvent.getResults() is null in devmode

[Benjamin Seber]

Hi,

I'd like to upload an image and get it's serving URL through GAE ImagesServiceFactory.

I've found this tutorial: http://ikaisays.com/2010/09/08/gwt-blobstore-the-new-high-performance-image-serving-api-and-cute-dogs-on-office-chairs/

Deployed on GAE it works perfectly. But running locally in devmode, there occurs following error in the javascript console:

Unsafe JavaScript attempt to access frame with URL http://t410:8888/upload?uploadedImageKey=xxx from frame with URL http://127.0.0.1:8888/photosharing/hosted.html?photosharing. Domains, protocols and ports must match.

Is there any workaround for devmode?

Try accessing your app using http://t410:8888/ instead of http://127.0.0.1:8888/

You'll likely have to pass the "-bindAddress t410" or "-bindAddress 0.0.0.0" option to the DevMode though: http://code.google.com/webtoolkit/doc/latest/DevGuideCompilingAndDebugging.html#What_options_can_be_passed_to_development_mode

Note that I never developped for AppEngine; there might be a way to tell the BlobstoreService#createUploadUrl to use http://127.0.0.1:8888/ as a prefix to the generated URL.
