If you place sequence diagram (and its lifelines) as a child diagram under any element and you apply time aware modelling on containing package, then if you clone element under which the sequence diagram is placed, new sequence diagram looses all messages.
Note: this happens on EA 14 and 15.
Investigation in DB shows, that in such case EA creates copy of original message, however there is not update in t_connector.DiagramID which still points to previous version diagram
Steps to Reproduce:
1) create package called ForVersion
2) create root diagram (custom)
3) create element (e.g. Use Case) and place its link on diagram
4) create sequence diagram and place it under Use Case
5) make UC composite
6) create another package called Catalogue and create two components in it
7) create one operation on on component
place components as lifelines on sequcence diagra
9) make call message from one component to the one with operation defined
10) link call to that operation in properties windows
11) save all diagrams
12) clone ForVersion package as a new version and name it ForVersion 2
13) open root diagram of ForVersion 2
14) clone use case as a new version
15) open sequence diagram under cloned version
Expected: Diagram displays sequence diagram with new version of lifelines and with message between them
Result: There are no messages displayed
Proable cause: copy of message connector was created with t_connector.DiagramID pointing to original sequence diagram instead to new one)
PS This is very critical issue for our company (bank with 1000+ empl.), as we have allready started using Time aware modelling for logical version control, thus I am copy&pasting it to this forum even though I have reported it allready
