I am having trouble running my workflow in an Xpand/Xtend M2M/M2T project.
Basically, I have a object model, I generate from it a relationnal model using Xtend, and from my relationnal model I want to generate SQL code using Xpand (I need the M2M because I'll use the object model to generate other stuff).
The M2M part works, the outmodel.xmi file is created with the data.
From the error message I get, I believe that as I load 2 metamodels, my workflow doesn't know which one to use once I try to load my outmodel.xmi
Workflow :
<workflow>
<property name="src-gen" value="src-gen" />
<property name="relationnalmodel" value="src-gen/outModel.xmi" />
<bean class="org.eclipse.emf.mwe.utils.StandaloneSetup">
<platformUri value=".." />
<!-- first ecore -->
<registerEcoreFile value="platform:/resource/genCPP/src/metamodel/metamodel.ecore"/>
<!-- second ecore -->
<registerEcoreFile value="platform:/resource/genCPP/src/metamodel/relationnel.ecore" />
</bean>
<!--read the model -->
<component class="org.eclipse.emf.mwe.utils.Reader">
<uri value="src/Model.xmi" />
<modelSlot value="model" />
</component>
<!--transform the model -->
<component class="org.eclipse.xtend.XtendComponent">
<metaModel class="org.eclipse.xtend.typesystem.emf.EmfRegistryMetaModel" />
<invoke value="object2relationnal::object2relationnal::transform(model)"/>
<outputSlot value="newModel"/>
</component>
<!--write the new model -->
<component class="org.eclipse.emf.mwe.utils.Writer">
<modelSlot value="newModel" />
<uri value="${relationnalmodel}" />
</component>
<!-- load the new model and store it in 'newModel' -->
<component class="org.eclipse.emf.mwe.utils.Reader">
<uri value="${relationnalmodel}" />
<modelSlot value="newModel" />
</component>
<!--once model is loaded, generate SQL tables and SQL procedures-->
<component class="org.eclipse.xpand2.Generator">
<expand
value="object2relationnal::SQL::main FOR Base" />
<outlet path="${src-gen}" >
</outlet>
</component>
</workflow>
Error Message (I cut the beginning) :

From the message, it seems I made at least two mistakes in workflow.

Maxime
One day I shall master M2T, but that day has yet to come...
