Edit internal messages

Hi community,

because of our agents (1st Level-Support) do not work all together at teh same time, I insert another dashlet "Internal Messages". Therefore I copied the functionality of "AgentTicketPhone". This means, all this posted internal messages are tickets.

The mask for posting a message contains only an edit-box for the subject and another for the content. All other fields are prefilled and disabled.

Now I try to add a function to edit a message afterwards it was created.

Here is, what I achieved till now:
1.) File: ArticleEdit.pm
Directory: /Kernel/Output/HTML/FilterElementPost

This file provides a button "Edit" into the articlemenu and the corresponding link.
 
2.) File: AgentArticleEdit.pm
Directory: /Custom/Kernel/Modules

Tis file contains the calling function:
my $Success = $TicketObject->ArticleUpdate(
  ArticleID => $GetParam{ArticleID},
  UserID    => $Self->{UserID},
);

3.) Core-file (Standard Core-File of OTRS)
File: Article.pm
Directory: /Kernel/System/ticket

This file contains:
=item ArticleUpdate()
update an article
Note: Keys "Body", "Subject", "From", "To", "Cc", "ReplyTo", "ArticleType" and "SenderType" are implemented.

    my $Success = $TicketObject->ArticleUpdate(
        ArticleID => 123,
        Key       => 'Body',
        Value     => 'New Body',
        UserID    => 123,
        TicketID  => 123,
    );

    my $Success = $TicketObject->ArticleUpdate(
        ArticleID => 123,
        Key       => 'ArticleType',
        Value     => 'email-internal',
        UserID    => 123,
        TicketID  => 123,
    );

Events:
    ArticleUpdate

=cut

sub ArticleUpdate {
...
}

4.) Output-File for edit-mask
A *.tt file, that provides a mask with to editboxes and a button to update the message.

Now, when clicking the button "edit" in a zoomed message (ticket), a new Popup-window appears and I could edit the subject or the content. 

But when clicking the button "update", an error-screen appears and the otrs-logfile contains the following error-message:
[Error][Kernel::System::Ticket::Article::ArticleUpdate][2074] Need Key!

I know, the Key is needed for the SQL-Statement to update the corresponding field into the database.

How could I set this value for "Key"?

Thanks in advance.

Sepp
