249452 - Copying header-only message between folders is confusing

Status: NEW

(MailNews Core :: Networking: POP, defect)

Description

[Mike Cowperthwaite]

Using the new-to-1.8 feature for downloading only the headers of POP mail:

When a new message has its headers downloaded, you can then drag the message to 
another folder, and holding down the Ctrl key during the drag makes a copy of 
the message.  Assuming local/POP folders (ref bug 249445), displaying this 
message in either folder shows the same "Not Downloaded / click here to download 
rest" notice.  This operation will work in either location.

However, if the message is removed from the server during the download of one 
instance (server setting: "leave message on server" unchecked), when the "click 
to download" link is clicked in the second instance of the message, it fails.  
The message entry is removed from the threadpane with no indication of a 
problem; the preview pane continues to display the Not Downloaded notice 
(similar to bug 192870).

(I notice that the case of "leave on server / until delete", then: Move to 
AFolder, OR {Copy to AFolder, Delete from Inbox}, and then downloading from 
AFolder, works -- that is, the message is downloaded when the link is clicked.)

I'm not sure what might be done about this.  Ideally, a headers-only message 
would simply not be allowed to be copied, but that's probably a hard thing to 
do.

Bug 248742 Comment #4 can describe why second(copied) partial message was lost
after additional download of first partial message.
So set dependency to it.
