questions while applying extension [message #475589]

Hi,

I tried to apply the heavyweight extension steps that published in the
"Extending UML2:Creating Heavy-weight Extensions" article, but I have some
problems.

1. I think that those steps belongs to a middleweight extension rather
than a heavyweight, where there is no a package merge or a package import
in the extension model. please, I need your comment.

2. It is mentioned that there is a zip file attached with the article, but
I didn't find it. Could tell me how can I get it?

3. I applied the mentioned steps, but after the code generation I found a
warning states that " Discouraged access: The type ActorImpl is not
accessible due to restriction on required project org.eclipse.uml2.uml".
When I tried to run the generated code, I didn't find my model in the
examples EMF model creation wizard as stated.

thanks in advance,

Sally

Yes there was a change in terminology somewhere along the way. This article
was created a while back and then another presentation came out with
slightly different conventions. This particular article is in a *rough*
draft form and hasn't officially been published yet. All the officially
published articles should be consistent and this one will be when it is
completed. ... sorry about the painfully long delay. So far these are the
only published ones

Since the article is not official yet, the links to such code has not yet
been set up.

I'm not sure about that issue. I'll have to retrace the steps outlined in
the article to see what is going on. Since the article was originally
created a *long* while back, there might be some subtle steps missing.
Consider this article a rough guideline for the time being.
If I'm not mistaken, others have used this article to get up and running.
You might want to search the newsgroup or perhaps others can comment on
their experiences.

The warning about discouraged access is expected since the UML2
implementation classes are considered internal - this is one of the reasons
why middleweight extensions are discouraged.
