Visio 2010 UML Object Lifeline renames itself when a Message is deleted

Question

I'm doing a lot of documentation for the way our systems interact with other systems and am using the UML Sequence Diagram (Metrics US) shapes that come with Visio 2010. When I use them, I have the following problem:

I create an object lifeline and name it 'X' then i add another object lifeline and name it 'y'. I add a Message from 'X' to 'Y'. This is all fine up to this point. BUT if I delete the Message that connects 'X' to 'Y', the object lifelines rename themselves to Object1 and Object2. You can imagine how annoying this is when you have about 10 different object lifelines and the fool thing decides to rename your all of your lifelines because of a deleted message!

I couldn't figure out why it was happening in the Developer tools section of visio either (though I'm by no means a Visio dev)

Visio 2010 Premium v. 14.0.5128.5000

Anyone have any insights?

Answer 1

For anyone having the same problem, I think I kind of found out what is causing it. If you rename an object by simply pressing F2, the problem occurs. However, if you rename it by double-clicking and entering the name, the problem disappears (at least so far).
