Access to model elements in referenced EPackages?

[Jörn Guy]

I am trying to list the contents of a model instance, as a start. The
instance loads in an editor plugged intor the design-time-workbench,
so the metamodels are all registered. Tefkat loads the content, but
does produce any out put. I have produced a minimal test case below.

The only thing that is different from the standard examples is that I
have my metamodel broken into several packages. The instance is
contained in a single container, however. Does this affect Tefkats
ability to match elements? Are the elements lazy-loaded and hence do
not show up when Tefkat enumerates candidate elements in the extent?

Hi Jörn,

Your rule is producing output here:

INFO: [list::r/Repository@platform:/resource/au.edu.uq.itee.mdavv.wrsa.foxbus.test2code/instances/My.code]
[] []

Which indicates that the rule is finding a single Repository instance
but no Component or DesignTime instances (with names). This looks
possibly correct to me since, from my reading of the XMI below, the
instance with name="Basic Calculations" is of the class "Component" in
the http:///au/edu/uq/itee/mdavv/wrsa/foxbus/modelManagement.ecore
namespace but the transformation is probably resolving Component to a
class from here
http:///au/edu/uq/itee/mdavv/wrsa/foxbus/designtime/components.ecore?
However, I'm just guessing at causes here (I don't parse XMI :-) What
happens if you try to match the objects in separate rules?
