i am evaluating this product as well and find that the reverse engineering feature does not work. I create a class diagram in VP and update eclipse - no problems. but then i create a class in eclipse that extends previous class. when i update VP-UML in eclipse, and go to VP, new class does not exist.
Please make sure you have Auto Synchronization turned on. If this option is turned off, you have to press the Update Code button every time you have modified the models. The Auto Synchronization option can be found at Modeling > Auto Synchronization.
If your problem still persists, could you please tell me more details about your working environment, such as the build number of the SDE, eclipse version, OS also the vp.log file? You can find the vp.log file inside the eclipse installation directory. If you don’t want to disclose such information in the forum, please send it to my private message box or email@example.com. Thanks in advance!
