I can’t seem to get the parameter list to show when I use a call message type between two lifelines. I setup the message to point to an operation of the ending lifeline’s class type, however, it shows up without parameters, i.e. send() instead of send(parameters). Even when I double-click on the item as if to edit the listing shows the correct signature with parameters and return type but when selected they disappear and only the empty signature remains.
