Re: SuperDevMode and same origin policy

Hi

This is an old thread but I have similar SOP issue:

I have a host page in the root of the webapp: /index.html

I also have a web worker on public path which ends up in /worker/Name.worker.js

I'm starting the worker using 'new Worker(<absolute url to worker file>); which is based on GWT.getModuleBaseUrlForStaticFiles();

The problem is when running in SDM public path is hosted from CodeServer and not from DevMode server where host page is located:

http://localhost:8888/index.html

http://localhost:9876/<module name>/worker/Name.worker.js

Is there any workaround for this except moving worker file from public path to webapp directory?

Hi Thomas,

Thanks for you answer.

Following your suggestion ( new Image(myImageResource) ), there is no more security error :)

All my textures are loaded but are almost empties. According to WebGLInspector all textures have size 1x1 with a transparent pixel.

It looks like that the HTMLImageElement obtained via image.getElement() is not properly filled now.

An idea about that ?

The image then is probably a "clipped image" using a sprited image: the image itself is a 1×1px transparent gif (clear.cache.gif, served from the same origin as the app) and the image is set as its background, with background-position and clip to only show the portion of the sprited image that corresponds to the original image. That makes me think we should add a isComplete() or isSprited() to ImageResource to "optimize" the way we create Image widgets out of ImageResources (which I happen to have already proposed in issue 7403).

Anyway, that explains why the security error has vanished.

So in the mean time, revert to "new Image(myImageResource.getSafeUri())" (no need to use asString(), there's an overload taking a SafeUri argument), but then I bet you'll have the security error back…
