Validation alerts on page load are not read

[MrGamble2]

As part of a government requirement I have been updating a website to meet standards. We run ASP.NET and when you submit a page and backend validation fails (can't find account during a login, account locked, unexpected server outage, etc) the page is actually reloading and errors are just passed with the model and displayed as statically loaded elements. I believe this to be relevant discussion to the issue I am facing: w3c/aria#1360

I would think that like JAWS, NVDA should support reading role="alert" on form load so developers don't have to add extra JS to get the error to read for NVDA. I'm changing our implementation for now but was curious if I am just missing something here or if its a feature worth discussing. Thanks!

@MrGamble2, Is it possible for you to provide an example page which demonstrates this behavior? Use codepen or jsfiddle or the like. Though I believe this has been discussed before. cc @jcsteh @aleventhal

Hey, so something as simple as https://jsfiddle.net/veon2x1m/ would be read by jaws. (though it isnt when in jsfiddle for some reason) Maybe its just a quirk of JAWS and it doesn't see the asp.net reload as a new page? Someone tested in the linked aria thread so it should work on a basic page load like jsfiddle as well I would think.

@jcsteh any suggestion here? I think alerts are only read when an action is performed, but not when the page is loaded. Is aria errormessage more appropriate? for this use case?
