526382 - Menus on the menu bar can't be modified while showing

Status: RESOLVED WONTFIX

(Mozilla Labs :: Jetpack Prototype, defect)

Description

[Drew Willcoxon :adw]

On OS X only, menus in the menu bar can't be modified while they're showing.  Trying to modify a menu in the menu bar as the result of some asynchronous call just before the menu is shown, for example, will appear to do nothing:

  jetpack.menu.add({
    label: "Doesn't Work on OS X :(",
    menu: new jetpack.Menu({
      beforeShow: function (menu) {
        menu.set("Loading...");
        foo(function (stringArray) menu.set(stringArray));
      }
    })
  });

where foo() is some asynchronous function, like an XHR.  The menu will continue to show the "Loading..." item even after foo() returns.  (If foo() is synchronous, no problem.)

This is due to missing functionality in Gecko unfortunately.  I'll file a bug there and make the dependency.  If/when that bug is fixed, this one will be, too.

Platform bug is bug 526387.

[Daniel Buchner [:dbuc]]

We will be monitoring all these issues after the rebooted Jetpack code base is released in the first week of March to ensure their causes are not duplicated. Many of the bugs/issues with the prototype version of Jetpack will be made irrelevant given the structure of the new SDK.
