I use some source code to run UMLDesigner, why sirius can add elements to the diagram, but the last open diagram can not be displayed when rerunning, some elements will be lost

Hello,

I don't know what happens in your source code, but the editor indicates that something is unexpectedly null. Can you open the "Error log" view and copy the stack trace with the Null Pointer Exception?

Regards,
Steve

Hi,

From your screenshot, it seems that your installation might be incomplete: if you compare with the screenshots on http://www.umldesigner.org/tutorials/tuto-getting-started.html for exemple, you will notice UML2 icons displayed in the model explorer when the model tree is expanded.

Furthermore I notice that your uc diagram is displayed in gray, this generally means that the "targeted" uml element (the element on which you created the diagram) no more exist. It also seems that you are in the Resource perspective and the Modeling Perspctive is not open nor active. You might need to check your installation.

How did you create the model, the diagram ?
Did you modify the uml model outside of UML Designer ?

Which version of UML Designer do you use ? or how did you install it in your environment ?

Regards,

Maxime

Thank you very much for your reply, I understand what you mean, the software is running without problems, I am compiling some of the source code to run.

There is no problem running now, but I still don't understand where the error is. I guess the reference to the uml element in Viewpoint is abnormal. I used to refer to the uml's jar package of eclipse. Now I am using the eclipse modeling development environment. The uml plugin already exists in the development environment.
This is the error message:
