IE: CoreControls: Uint8Array: "Typed array constructor argument is invalid"

[Chris Hine]

Hi Again,

I'm seeing an error originating from withing CoreControls.js when attempting to load a .xod (from Azure blob storage and using xhook to supply access params.) Specifically on the (minified) line 355: var e=new a.Uint8Array(k) where k is "P". This prevents the document from loading.

I note that "foo = new Uint8Array("P")" does produce the error in the IE console but not in Chrome. Strange part is that the .xod loads successfully in Firefox and Chrome yet "foo = new Uint8Array("P")" does yield the error in the FF console whereas is does not in Chrome.

In case it's useful, despite the minification, here's the call stack:

Hi Chris,

If you load the same XOD file from a local server (not using xdomain.js) are you able to load it?

Hi Matt,

Yes, I can load the same XOD from a local server (both with and without xdomian being specified to the webviewer) using IE. IE 11.0.9600.17498, in case it's relevant.

Thanks,

Chris

Anybody home?

Hi Chris,

I just got back from vacation and it looks like this one slipped through the cracks while I was away. Sorry about that!

So it seems like this only occurs in IE and when the document is on Azure blob storage?

Is it possible that you could supply a publicly accessible link for me to try out a test page to be able to debug the issue more easily? If you don't want to post it here you can email it to mpar...@pdftron.com.
