1190166 - When opening New Task dialog: 'Assert failed: aElement' thrown

Status: RESOLVED FIXED

(Calendar :: Tasks, defect)

Description

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

Thunderbird 38.1.0, 40.0b1 and 42.0a1 20150801 on Windows 8.1

Clicking the New Task button in the toolbar opens the dialog but throws:

Timestamp: 02.08.2015 13:11:25
Error: Assert failed: aElement
2: [chrome://calendar/content/calendar-ui-utils.js:27] setElementValue
3: [chrome://calendar/content/calendar-ui-utils.js:81] setBooleanAttribute
4: [chrome://calendar/content/calendar-event-dialog.js:555] loadDialog
5: [chrome://calendar/content/calendar-event-dialog.js:297] onLoad
6: [chrome://calendar/content/calendar-event-dialog.xul:1] onload
7: [null:0] null

Line: 1001

This happens when button-freebusy gets hidden.

I can see this on trunk, just clicking Write->Task.

This bug has been fixed with the patch for bug 1229148.
These code lines in the patch are reserved for this bug:
https://hg.mozilla.org/comm-central/rev/95367f284f9e#l2.12
they prevent the call to setElementValue with a null parameter (aElement="free-busy") when the free-busy button is hidden in the dialog.

makemyday, I set the assignment to you because you wrote a fix.
I think we can close this as fixed.

Thanks. Yes, we can consider this to be fixed with bug 1229148 already.
