An other problem.
I have an activity diagram with swimlanes (vertical)
After checkin to teamserver the swimlanes are still in the project, but some of them lost the name of the partitions. In the specification of the swimlane is no partition, but on diagram the vertical partitions are shown.
I notice that you are using quite an old release of VP Suite 3.0 SP1. We have recently fixed a number of problems regarding to the Teamwork Server, SVN and CVS integration, especially for containment problem like swimlane to partition. Could you run the product updater to advance to the latest release, and try again? You can find it under the bin folder of VP Suite installation folder.
If this is still problematic, could you send us your project file and let us know which kind of teamwork integration (Teamwork Server, SVN, CVS) are you using?
