I will send Message only an customer but without in Ticket, in the Trigger for example by Tickets Owner changed:
msg.send(vTO, vCC, vBCC, subject, body);
Or I comment out with msg.setValue("1", ticketId);
then each time I get Error in Ticket after Ticket Owner changed:
Something went wrong, an error message is logged with current time: ...
If i refresh ticket again, it displays all correctly, but the message was not sent out.
How could i send Messege in trigger without associated in ticket?
