java code generation [message #1790272]

I have two classes say A and B where B is a generalization of A.

When I run the java code generator I expected the code to look like

public class B extends A {
...
};

but I just get public class B { ... };

So my questions are:

does Papyrus Designer currently support generating code for generalization edges?
where can I find the documentation that specifies what is and what is not supported?
is there any other documentation regarding generating java code. eg how can I represent a set?

Thanks,
Steve

That's odd, I get well the following code for B (having a generalization on the model level):

public class B extends A {
};

are you sure that you used a generalization (and not for instance a realization relationship). Which version of SW designer do you use?

Looks like 1.0.5 for "Papyrus Java profile, library and code generation (Incubation)" although its parent "Papyrus Designer Transformation, develop and deploy component based applications (Incubation)" shows version 0.7.6.

While the Java code generation has not been touched recently (as far as I know), could you please upgrade to a nightly version using the following update site
https://hudson.eclipse.org/papyrus/job/papyrus-designer-oxygen/lastSuccessfulBuild/artifact/releng/org.eclipse.papyrus.designer.p2/target/repository/
(the job is build against Papyrus oxygen, but can also be installed on photon).
If you still have the problem with the nightly version, could you eventually post your model (or via private mail), so that I can check whether I can reproduce the problem.

Ansgar,

Last night I ran the same thing on a different computer an it worked as expected so there must be a problem with the setup or configuration on this particular computer. The good news there is that the software is OK.

Do you have any suggestions for where to start investigating?

Thanks,
Steve

So I've found that this has something to do with visibility.
I was organizing my classes and moved a class into a different package then next time I generated the code I got the extends keyword.

I'll have to try to determine exactly the circumstances in which the extends keyword does not get generated.

If someone already knows, please let me know.

Thanks,
Steve

I was having a similar problem while trying to generate Java code on Photon via Papyrus. Updating the nightly build version of Papyrus Designer solved the problem.
