In sequence diagrams, you can change the source lifeline
or target lifeline of a message to reconnect the message to the new
lifeline.
To reconnect a message to another lifeline:
- Open a sequence diagram that contains existing
lifelines and messages.
- In the interaction frame, complete one of the following
steps:
- To reconnect a message to a different lifeline,
click a message handle and drag it to another lifeline. The message
is reconnected to the new lifeline.
- To reconnect a message on the same lifeline, click a message
handle of a synchronous, asynchronous, or destroy message and drag
it to the same lifeline. The message becomes self-directed and the
send message appears higher than the receive message.
