The sequence numbering in EA allways starts at 1.0, I think. The next messages are numbered with 1.1, 1.2, 1.3 aso.
If you right-click a message arrow and select [Activations]->[Start New Message Group], this message is numbered with 2.0 and any following with 2.1, 2.2 aso.
As far as I can see, the numbers you are printing are corresponding with the order of the sequence numbers. In my diagram 1 means 1.0, 2 means 1.1, 3 means 1.2, 4 means 2.0, 5 means 2.1 aso. So the order seems to be correct; maybe you have to count the numbers by your own and trigger on a flag like “new sequence” or something like that.
My sorting problem only occures with more than 9 messages. You seem to order alphabetically, not by number – so “10”, “11”, “12” is sorted before “1 “.
Maybe you can have a look at this too in the next release – thanks!
