Hey guys,
I'm working on a project where Papyrus has been added to an Eclipse RCP project. Most things are working for now, but the attached exceptions are logged into the console on startup.
The org.eclipse.papyrus.uml.diagram.common plugin should include the editparts or am I missing something?

It very much should indeed. From the trace I assume you are using the 2020-06 release (4.8.0) ? can you see if the included jar do contain any of the mentioned classes (I just checked in the released jars and it is indeed there) ?
Are you importing/depending on the associated packages or is the common plugin correctly loaded when the RCP starts ?
Cheers,
/Quentin
Hey and thank you for your replies,
Yes, I'm using the 2020-06 release, after updating from 2020-03 to see if the exceptions are fixed. The included jar does indeed contain the mentioned classes.
I'm new to the project and Eclipse RCP, so I'm not exactly sure what you mean, but the plugin is included in the run configuration.
Cheers,
Bernhard

Hi
Not sure if it's the problem here, but when I need to refer to a class by textual name, e.g. "XXX", I generate the text by XXX.class.getName() thereby ensuring that XXX is correctly spelled and that any refactoring takes effect and that searches hit. Never type it independently. If you have a dependency problem, use a builder to auto-generate a file containing some upstream constants that are defined to reference downstream values.
Regards
Ed Willink
