Trouble resolving sub-packages via URI [message #138989]

Not too sure if this is the correct newsgroup, EMF? EMFT?

Anyhoo:
I have an Ecore file with the root package called: First and a NS URI of
"http:///First.ecore"

In the ecore model there is a sub-package to First called Second, which
has a NS URL of "http:///First/Second.ecore"

I'm running a workflow to do a M2T transformation, however I get stuck
just trying to read in my XMI file, since it can't resolve the Package
"http:///First/Second.ecore". (stack below).

Any pointers would be great!

First2csv MWE:
<?xml version="1.0"?>
<workflow>
<property name="model" value="platform:/resource/first/test/uber.first" />
<property name="out" value="out" />

<bean class="org.eclipse.emf.mwe.utils.StandaloneSetup">
<platformUri value="../" />
<RegisterEcoreFile value="platform:/resource/first/model/First.ecore"/>
</bean>

<component class="org.eclipse.emf.mwe.utils.Reader">
<uri value="${model}" />
<modelSlot value="model" />
</component>

<component class="org.eclipse.xpand2.Generator">
<metaModel id="mm"
class="org.eclipse.xtend.typesystem.emf.EmfRegistryMetaModel " />
<expand value="first2csv::Main FOR model" />
<outlet path="${out}" />
</component>
</workflow>

Hi Refux,

as far as I can see from the code, registerEcoreFile does not register
subpackages but only the root content of the ecore resource.
Please file a bugzilla against mwe.

A workaround would be to use generated ePackages instead of dynamic
instances.

Regards,
Sebastian

Thanks for the info, I will file a bug.

As a temporary workaround I am manually placing:
xsi:schemaLocation="http:///First/Second.ecore
.../model/First.ecore#//Second" in the XMI file.
