I have installed the Papyrus Designer. I have created a class diagram. But when I right click and choose Designer> Generate Code I get an error message "The chosen operation is not enabled".

I have worked with the Designer previously and been able to Generate Code. Any ideas?

Hi,

I did ran into the same issue. I tried a lot of things to get this back working, including reinstalling Eclipse, the Papyrus main and Designer plugins. But nothing seemed to help, although I could generate code for a new project.
Finally I found out that I could resolve the issue by removing spaces from the Eclipse project name.
Maybe this helps to resolve your problem too.
Regards,
Sander

It sounds like the code generation plugin is missing. You can install it using the Help->Install new software... menu option.

There are several code generators. I personally use Papyrus to generate C++ code, but perhaps you want the Java generator.

Hi,

I can confirm that the handler code fails in case of spaces in the project name. The code checks whether the project hosting the model exists. This fails, if the obtained project name contains spaces, as they are encoded as %20. Please post a bug.

Best regards
