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
