Hi OTRS-developer, to post internal messages for our agents, I tried to insert a new module called AgentMessageAdd. This messages should be displayed on dashboard in a new widget. I achieved this goal on our OTRS 4-Instance. So I did the following: 1.) Registration of the module File: Message.xml Directory: /Kernel/Config/Files With this file I get the entry "Messages" into the menuBar and register the module. This works! 2.) Configuration of the mask, to post a message File: MessageConf.xml Directory: /Kernel/Config/Files After this, I can configurate the mask via SysConfig. 3.) Functionality File: AgentMessageAdd.pm Directory: /Custom/Kernel/Modules This is a modified copy of file "AgentTicketPhone.pm". Changes: package Kernel::Modules::AgentMessageAdd; ... # get output back return $LayoutObject->Output( TemplateFile => 'AgentMessageAdd', Data => \%Param, ); 4.) Mask File: AgentMessageAdd.tt Directory: /Custom/Kernel/Output/HTML/Templates/Standard This is a copy of file "AgentTicketPhone.tt". Calling the function "Post new message", the mask opens and a new message could created as a ticket. But when clicking the Button "Create", nothing else happens. unfortunately, there's no entry in the OTRS-Logfile or the Apache-Logfile. I think, the new module uses the Core-Module File: Ticket.pm Directory: /Kernel/System so, I don't have to develope a new Core-Module for this module. Do I have to register this new module anywhere else? Is there anything missing? Thanks in advance. Sepp
