----------------------------------------
Hi Ron,
only just seen your comments. The xsd for the Customer class is
CustomerAccount.xsd I think in the tools project src/test/resources folder.
This is highlighting the fact that we don't have a good story on
exercising/testing the tools project, in that if we did, all these things
would be regenerated every time we did a maven build. I added some code to the
generator so that, tucked away inside the FactoryImpl class is a record of the
arguments (that I could lay my hands on) which were used for the generation of
the set of classes. For example, I see by that means that the generation of the
CustomerAccounts class used a specific -prefix argument.
There's a description of how to regenerate the core models in
ModelFactoryImpl.java. My feeling is it would be best to regenerate the core
models.

> Hi Ron,
> Looking at this, it looks like the problem is that you're trying to create
> dynamic subclasses of statically generated types. The bad news is that
> Tuscany doesn't currently support that. The good news is that it's not too
> hard to add the support.
> The problem is that currently Tuscany only has these two primary
> DataObject implementation classes:
> 1. DataObjectImpl - is the base class used for statically generated types.
> It is highly tuned for performance and footprint, so, unlike the base
> class in SDO1 (actually EMF) it doesn't support dynamic extensions.
> 2. DyamicDataObjectImpl - is the class used to support dynamic SDOs. It is
> designed for pure dynamic types, not a mixture of static and dynamic.
> To support what you want, we will need another base class, say
> ExtensibleDataObjectImpl, that is quite similar to DynamicDataObjectImpl,
> but doesn't make the assumption that eStaticFeatureCount() is 0. My guess
> is that there are only a few simple method overrides needed in this class.
> Maybe you would like to try to prototype such a class yourself and hand
> modify your generated classes to extend from it? If you did that and
> tested it, you could submit a patch and we could then very quickly add a
> generator option to use it (maybe even make it the default). If you'd like
> to help with this, it would be very much appreciated!
> At any rate, you should probably open a JIRA feature request for this.
