I have been trying for few days now to set up the mwe workflow file for xpand generator I am trying to build.

The problem is the i have separated my:
1. metamodels
2. m2t qvt transformations
3. output instances of m2m transformations
4. xpand templates and workflows

into 4 separate projects (respectively).

I managed to reference them all, and the editor for xpand template file is properly reading metamodels (e.g. ctrl-space in template editor gives me list of metamodel elements).
However, when I run my generator.mwe file, it gives me following error:

Here is the source for generator.mwe file:

	<property name="out" value="src-gen" />
	
	<!-- set up EMF for standalone execution -->
	<bean class="org.eclipse.emf.mwe.utils.StandaloneSetup">
		<platformUri value=".."/>
		<RegisterEcoreFile value="platform:/resource/generatorMetamodels/model/ejb3.ecore"/>
	</bean>

	<!-- load model and store it in slot 'model' -->
	<component class="org.eclipse.emf.mwe.utils.Reader">
		<uri value="${model}" />
		<modelSlot value="model" />
	</component>
	
	<!--  generate code -->
	<component class="org.eclipse.xpand2.Generator" id="generate">
		<metaModel id="mm" class="org.eclipse.xtend.typesystem.emf.EmfRegistryMetaModel"/>
		<expand value="EntityBeanTemplate::entityTemplate FOR EntityBean" />
		<outlet path="${out}"/>
	</component>
</workflow>


Can anyone help me, please? Sad

Hi,

<expand value="EntityBeanTemplate::entityTemplate FOR EntityBean" />


should be

<expand value="EntityBeanTemplate::entityTemplate FOR model" />


since yiu stored the model in a slot named "model" in the reader

<modelSlot value="model" />
