572139 - File.url from a dropped file doesn't work as source for images

Status: RESOLVED FIXED

(Core :: DOM: Core & HTML, defect)

Description

[Paul Rouget [:paul]]

Setting the src attribute of an image element with the url property of a File object doesn't work.

See the test here:

This worksforme if I select the file using an <input type="file">.  And for the drop case, if I look at my error console I see:

  Security Error: Content at http://people.mozilla.com/~prouget/bugs/fileurl.html
  may not load data from moz-filedata:ab11527f-ad10-2a41-928f-50a676a4a381.

So presumably we're not giving dropped files the principal of the page we drop into.  Perhaps we should.

Thanks for finding this. We should indeed give dropped files the correct principal.

Any update here? I'd like to use File.url in my coming demos :)

Just a note to say that I get this crash every time I try to use File.url

Kyle, does your patch for bug 594964 fix this?

Yes.

This should be fixed now, though the syntax is no longer file.url.
