1402745 - on moving a calendar tab: currentView(...) is undefined

Status: NEW

(Calendar :: General, defect)

Description

[Guy K. Kloss]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:55.0) Gecko/20100101 Firefox/55.0
Build ID: 20170816204344

Steps to reproduce:

I have intentionally or unintentionally (drag/drop out of the window header) removed the Lightning Calendar tab out of the Thunderbird main window.
Also, when popping the tab back into the main window, the calendar still does not function again.


Actual results:

The calendar becomes unusable: Using any UI navigation elements of the Lightning calendar fail (change of date, moving forward/backwards).


Expected results:

Normal operation of the Lightning Calendar with all UI elements. At least after re-attaching the calendar tab to the main window.

The first two exceptions shown in the debug console when this happens:

Forgot to mention: Restarting Thunderbird fixes the problem with the view.

Confirmed.
Steps to reproduce slightly different than bug 722353 comment 8 but it seems a very similar bug.
