825797 - wait_for_message_display_completion does not work after switch to wide mail layout

Status: UNCONFIRMED

(Thunderbird :: Testing Infrastructure, defect)

Description

[Joachim Herb]

Attachment: Sample mozmill test file

In a mozmill test the function wait_for_message_display_completion from shared module folder-display-helpers.js does not work (i.e. runs into timeout) if the View->Layout->Wide is chosen (see attached sample mozmill test file).

A work around is to close the 3pane window and reopen it:
  let abwc = openAddressBook();
  close3PaneWindow();
  mc = open3PaneWindow();
  abwc.window.close();
function openAddressBook() {
  let windowWatcher = Cc["@mozilla.org/embedcomp/window-watcher;1"].
    getService(Ci.nsIWindowWatcher);
  windowHelper.plan_for_new_window("mail:addressbook");
  windowWatcher.openWindow(
                      null,
                      "chrome://messenger/content/addressbook/addressbook.xul", "",
                      "all,chrome,dialog=no,status,toolbar",
                      null);
  return windowHelper.wait_for_new_window("mail:addressbook");
}

Forgot this function for the workaround:
function open3PaneWindow() {
  let windowWatcher = Cc["@mozilla.org/embedcomp/window-watcher;1"].
    getService(Ci.nsIWindowWatcher);
  windowHelper.plan_for_new_window("mail:3pane");
  windowWatcher.openWindow(null,
                           "chrome://messenger/content/messenger.xul", "",
                           "all,chrome,dialog=no,status,toolbar",
                           null);
  return windowHelper.wait_for_new_window("mail:3pane");
}
