[Acceleo] Generator works with Papyrus, but fails with MagicDraw [message #1801559] Tue, 22 January 2019 14:46 Go to next message

I developed an Acceleo based generator which generates the metadata.xml file for an OData service which is modeled in an UML model created with Eclipse Papyrus.

After solving initial problems it works fine.

Because Papyrus is lacking some functionalities I need, I want to switch to MagicDraw.

I managed to import the Papyrus UML model successfully into MagicDraw.
I lost all diagrams, but the model itself was completely ok.

Now the problem:
When I export the model again to "Eclipse UML2 (v5.x) XMI" Acceleo code generation fails with a null pointer exception.
I don't know why and how to handle this problem.

I attached the Papyrus model, the MagicDraw model and the reexported model.

I use Eclipse Modeling Oxygen-2 and MagicDraw 19.0.

Thanks for your help! :-)

Hi

MagicDraw problems should be asked on a MagicDraw forum.

getSettingDelegate problems are usually due to bad registrations. I suggest you ensure that MagicDraw registers in the saem way as Papyrus.

Regards
