554745 - Possible to get into a locked modal UI state

Status: RESOLVED WORKSFORME

(Core :: Printing: Setup, defect)

Description

[Alex Limi (:limi) — Firefox UX Team]

Attachment: Deadlocked state

See screenshot for the state I'm talking about. 

There's a modal dialog showing "Print" options, and then the document seems to change underneath it (by some sort of page update event?), which results in a "Document cannot change while in Print or Print Preview"

When this happens, I can't dismiss the dialog's "OK" button, since I'm stuck inside the Print dialog, and I can't dismiss the Print dialog since it's waiting on the dialog box with the "OK" in it.

Only way to get out of it was to kill the process.

Which Firefox version?  I'd think not trunk, right?

It just happened to me on a Mac with release version 3.6.8.

We don't seem to have the string "Document cannot change while in Print or Print Preview" in the codebase any more, so maybe that dialog no longer exists. I don't seem to be able to trigger it, but then a few years ago we switched to cloning the original document for print, so this shouldn't be an issue any more.
