User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.8.1.11) Gecko/20071127 Firefox/2.0.0.11

In multiweek events get lost (they just disappear while holding the mousebutton). You can get rid of all events this way. Disappeared events "come back" if you switch to another viewmodus and back. This bug is present at local and remote calendars.

Reproducible: Always

Steps to Reproduce:
1. Go to multiweek
2. create a event (or just take one you already have) and grab this 
3. move the mouse to another day

Actual Results:  
The selected event disappears

Expected Results:  
The selected event should have moved to the selected day.

Drag and drop of events in multiweek view work fine for me using Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.12pre) Gecko/20080110 Calendar/0.8pre. Tested with storage calendar in new profile.

Works for me with the attached event using Lightning 2008011003 or Sunbird 20080110.

[Lars Wohlfahrt (thetux)]

I can't reproduce it myself on Lightning 2008010904

[Philipp Kewisch [:Fallen][📱📆]]

Lars, if you are able to reproduce please check your error console. I assume that you are dragging over a <tree> and its producing exceptions. Try all trees you can find :)

Hi Philipp,

we think that this two exceptions comes from the Nightly Tester Tools 1.3b4

Error: brandbundle has no properties

Line: 14

Error: document.getElementById("nightly-breakpad-sidebar") has no properties
Source File: chrome://nightly/content/breakpad/breakpad.js

I let some more events disappear and got this:

I found out, that they all reappear if i click on multiweek again (even it is already "pressed"/activated).

Comment 9

[Philipp Kewisch [:Fallen][📱📆]]

I think the culprit is 

Error: [Exception... "'JavaScript component does not have a method named:
"drop"' when calling method: [nsITreeView::drop]"  nsresult: "0x80570030
(NS_ERROR_XPC_JSOBJECT_HAS_NO_FUNCTION_NAMED)"  location: "JS frame ::
chrome://calendar/content/calendar-month-view.xml :: onxbldraggesture :: line
267"  data: no]
Source File: chrome://calendar/content/calendar-month-view.xml
Line: 267

In that case, this would be a dupe of bug 408657.

Comment 10

[Philipp Kewisch [:Fallen][📱📆]]

Lars, an example of how this should be done (for a different tree) is in the denoted bug, maybe you are interested in creating a patch for us?

Comment 11

[Stefan Sitter [:ssitter]]

Note: The 0x804a0002 error indicates that you are trying to edit or add an event in a read only calendar (see Bug 313640). You might want to retest with a writable calendar.

Comment 12

[Lars Wohlfahrt (thetux)]

Stefan, I don't what I can do about it. It is a clean profile with just the home calendar. I doublechecked it: the calendar is not marked as read only.

I also noticed this:

Error: [Exception... "'JavaScript component does not have a method named: "getParentIndex"' when calling method: [nsITreeView::getParentIndex]"  nsresult: "0x80570030 (NS_ERROR_XPC_JSOBJECT_HAS_NO_FUNCTION_NAMED)"  location: "JS frame :: chrome://calendar/content/calendar-month-view.xml :: onxbldraggesture :: line 267"  data: no]
Source File: chrome://calendar/content/calendar-month-view.xml
Line: 267


I think this wasn't there before.

Comment 13

[Lars Wohlfahrt (thetux)]

I have done crosscheck: when I set the calendar into read-only-mode, it is not possible to move the event.

Comment 14

[Philipp Kewisch [:Fallen][📱📆]]

the exception from c12 also means that the tree view is not implemented correctly. I'm marking this duplicate now.

[Philipp Kewisch [:Fallen][📱📆]]

Oops, wrong bug#
