Status: RESOLVED DUPLICATE of bug 305754

(Calendar :: Sunbird Only, defect)

Description

[Marcin Kost]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; pl; rv:1.8b4) Gecko/20050823 Firefox/1.0+

There are lots of problems with calendar selection and all of them give the same
JavaScript Console errors:

Error: this.parentNode has no properties
Source File: chrome://global/content/bindings/listbox.xml
Line: 761

Problems I found:
- when a calendar is first unchecked and then checked it is impossible to
uncheck it again,
- when all calendars are unchecked it is impossible to check any of them,
- random checking and unchecking of calendars (as long as at least one is
checked) gives strange results, seems like a puzzle game and I can't find the
logics behind this behaviour yet.

Reproducible: Always

Steps to Reproduce:
1. Create several calendars to populate the list
2. Play around with checking and unchecking them
3.

Actual Results:  
Following error appears in JavaScript Console:

Error: this.parentNode has no properties
Source File: chrome://global/content/bindings/listbox.xml
Line: 761

If all calendars are unchecked it is impossible to check any. Calendar can only
be deselected and selected once.

Expected Results:  
None of the above should happen.

Sounds like bug 305597, which was fixed yesterday.  Can you try again when
today's nightly becomes available?

Sounds similar, I'll give it a try and report the results.

Was the patch for 305597 in any way connected with the JavaScript Console error
I had?

it's a dup of bug 305754 for sure (which might be a dup of bug 305597)
