252210 - Modal dialog cannot open modeless dialog

Status: RESOLVED INVALID

(Core :: XUL, defect)

Description

[Alex Vincent [:WeirdAl]]

Discovered in Mozilla 1.7 RC1.

Basically, I had a modal dialog for my Abacus project (so the parent 
application could not stop it from executing).  The modal dialog would then try 
to open a modeless dialog (in my case, a floating menu).  Ideally, the user 
could still interact with the modal dialog.

In actuality, the sub-window was modal as well; I could not interact with the 
modal dialog while my supposedly modeless dialog was open.

This should be trivial to write a testcase for. :)

Some platforms used not to or still don't allow you to open a modeless window
with a modal parent. However you should be able to use the window watcher to
open a new top-level window. Look at openHelp in contextHelp.js for example.
