Re: [Evolution-hackers] on deleting folder

[Not Zed <notzed ximian com>]

Ahh, I see.  That sort of makes sense.

When the folder is deleted, it first deletes all the messages, the
folder will then emit a 'folder changed' event with all the message
uid's as 'deleted', so then the etree (which is used for the popup
window too) will remove all of its nodes, and finally it will emit a
'selection changed' event which clears the current message ...

I'm not sure how you could fix this, because of the MVC split.  It is
used to do things like skip to the next message when you delete the
current one.

You could probably try something like not clear the window if there are
no messages anymore, but that wont work if you have multiple windows
open on different messages on the same folder.

Really it seems to me however, the popup window should be removed in
this case, since although you will still be able to see the message,
many operations, like replying/forwarding/etc actually re-load the
message from the folder when they are invoked, and do not operate on the
in-memory image.  So it basically wont work.

To be honest, it seems a pretty bizarre feature to want, if you delete a
folder, that includes the messages inside it, viewed or not.
