[error] java.lang.NullPointerException where update a project

Hi, I’m having a problem with my VP server.

When I start to update the project, I get a pop-up error message: java.lang.NullPointerException.
A week ago everything worked fine, now it gives this error. When I try to create a new workspace, I do not take a checkout from the repository

Dear vikkiorrikki,

Thanks for your inquiry. Would you mind attach your log file? It can be exported from the About dialog.
If you don’t want to post in the forum, you can send it to support-team@visual-paradigm.com and include the link to this post in the Email.

Dear vikkiorrikki,

We checked your log file. Please try the following steps to solve the problem:

  1. Enable engineering mode in About Dialog
  2. Open “Teamwork Client”, enable “Validate diff before apply” in “Maintenance” menu
  3. Update/Commit project as usual

Unfortunately, "Maintenance” menu is missing. Only “Session”, “Project”, “Repository”.


Did you enable engineering mode and restart?


But…In the menu of the Teamwork Client nothing has changed

I’m sorry that missing one more step.
Please also enable “Advanced UI mode” in Application Option.
