Status: RESOLVED DUPLICATE of bug 398405

(Calendar :: Lightning Only, defect)

User-Agent:       Mozilla/5.0 (X11; U; SunOS i86pc; en-US; rv:1.9.1b3) Gecko/20090420 Firefox/3.1b3

If you are using Lightning - and you have the Today Pane open, showing tasks,
which reading e-mail - then if you mistakenly have a task highlighted, and then
press Delete, it quietly deletes the task - and it's not obvious what was just
deleted.

If you press Ctrl+Z, it undeletes an e-mail not the task. You have to switch to
the Tasks view to undelete the task - again not obvious... 

I would suggest that in the Today Pane you either confirm the deletion, or make
undelete work in that view correctly.

Is there anyway to force confirmation of the deletion of a task or event
without also requiring confirmation of the deletion of e-mails...?

I've reproduced this using TB3.0b3pre (2009-04-24) and Lightning 1.0pre.

Reproducible: Always

Steps to Reproduce:
1. Select a task in the Today Pane
2. Press the Delete Button
3. Try Undo from Edit menu (or simply Ctrl+Z)
Actual Results:  
Instead of undo-ing the deleted task, it undo a deleted e-mail.

Expected Results:  
Should know that it's got the Tasks area focused and undo should undo the deletion of the task.

It's very easy to make a mistake and set focus to the Tasks area in the Today Pane, and it silently deletes the task - and as such it's easy to miss the fact that it did this.
