No UML2 Properties in UML-sourced GenModel [message #476987]

Hi,

I am attempting to generate code from a UML model using the UML2 component's
codegen extensions. After I imported my GenModel from UML, I found that
the GenPackage doesn't have the UML2 properties (e.g., for the operations
package and resource interfaces) that I see in the UML.genmodel from the
org.eclipse.uml2.uml plug-in.

I notice that the UML.genmodel uses a specialized GenModel schema:

http://www.eclipse.org/uml2/1.1.0/GenModel

instead of the usual EMF GenModel:

http://www.eclipse.org/emf/2002/GenModel

which my genmodel references. I expect that this is related to the problem.

Is there anything I'm not doing, that I should be doing? I simply use the
UML importer in the New EMF Model wizard. I am using the UML2 SDK version
2.2.0 M5.

TIA,

Christian

Christian,

The UML2 generator model is only used if certain options are specified in
the import wizard - basically options that need to be processed by UML2
because they can't be handled by EMF (e.g. the options for redefinitions,
subsets, derived unions, etc.). If you choose 'Process All', you'll get the
result you want, or perhaps you could turn on one of the UML-specific
options I just mentioned. I've been thinking for some time that the
interface needs to be improved so that the user can explicitly specify (e.g.
with a check box) that a UML2 generator model be used; if you open a
Bugzilla request, we'll take a look.

Thanks, Kenn,

Setting the options to process subsetted properties, etc., worked. I find
that some of the options' labels are a little misleading, though. For
example, it isn't clear that there should ever be any value in not
discarding duplicate operations. It there are duplicates, why retain them?
I had assumed that "duplicate" was different from "redefining" ...

Anyhow, say "Hello!" to https://bugs.eclipse.org/220552

As I indicated there, I think UML2 offers enough value-add to the code
generation to always employ its specialized GenModel.

Christian,

EMF discards "duplicates" by default. UML2 support "processing" them, which
means it will generate overrides that you can implement to do something
different in subclasses.

Thanks for the bug - I agree that it should always produce a UML2 generator
model (see my comment on the bug).
