432704 - [Trunk] Drag and Drop in Month/Multiweek view fails [Error: this.parentBox is undefined]

Status: VERIFIED FIXED

(Calendar :: Calendar Frontend, defect, P2)

Description

[Stefan Sitter [:ssitter]]

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9pre) Gecko/2008050713 Calendar/0.6a1

Steps to Reproduce:
1. Start with new profile and switch to Month or Multiweek view
2. Create a new event
3. Drag and drop the event to a different day

Actual Results:
Starting the drag operation makes the event disappear. Error Console shows

  Warning: reference to undefined property this.parentBox
  Source File: chrome://calendar/content/calendar-month-view.xml
  Line: 229

  Error: this.parentBox is undefined
  Source File: chrome://calendar/content/calendar-month-view.xml
  Line: 229

Expected Results:
  Drag and drop operation starts and the event can be moved to a different day.

Additional Information:
  The following error (reported as Bug 402573) is also visible:

  Error: a._updateVisibleText is not a function
  Source File: chrome://global/content/bindings/textbox.xml
  Line: 208
  
  Maybe it is unrelated. Maybe it is the cause for the drag and drop failure.

Does this error still exist?
Could not reproduce it...

Yes. Issue still exists using Lightning 0.6a1 (20080922034402) with Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1b1pre) Gecko/20080922031046 Shredder/3.0b1pre.

Seems to happen 100% of the time for me.  It's somewhat scary, because it appears to be data loss (though it actually isn't, since the data has merely disappeared from view).

I could not reproduce this anymore and believe it has been fixed with 
Bug 416138 -  Moving of all-day-events in weekview not possible, but shows possibility
The errormessage a._updateVisibleText is not a function still occurs once in a while but as far as my experience goes - not in conjunction with drag'n drop

I checked this issue in lightning and sunbird build 20081207 -> VERIFIED.
