618878 - content page in a unit test doesn't have document object defined

Status: RESOLVED DUPLICATE of bug 614757

(Add-on SDK Graveyard :: General, defect)

Description

[Matěj Cepl]

Attachment: example reproducer

When I run the attached project via cfx run (this is defined for bugzilla.redhat.com, but should work on bugzilla.mozilla.org as well, but I don't have proper permissions to test it here), I have perfectly working content script. However when I run the essentially through essentially same pageMod command, I get error that document object doesn't exist in main().

If there is anything wrong with my script, then I would expect some more reasonable error message than this.

This is really really crazy. Just by switching from one project to another (without changing anything) tests start to fail:

[Matěj Cepl]

second project is http://gitorious.org/addon-sdk/test-page-mod-bug which is very simplified test just to make sure I know how to write pageMod tests.

Comment 5

[Irakli Gozalishvili [:irakli] [:gozala] [@gozala]]

So looks like this was related to:

https://bugzilla.mozilla.org/show_bug.cgi?id=614757

Which was regression in FF which is fixed now.

I'll keep this one open to make sure we add tests for this bug.

Comment 6

[Matěj Cepl]

Yes!!! This IS a duplicate of bug 614757, and it has been fixed in FF4b8

Thank you, Irakli!
