Hi,

I have a problem with xpand.
I have 2 ecore metamodel. The Scene metamodel includes the star metamodel.
This is my pwt file:


«IMPORT Scene» 
«IMPORT Star»

«DEFINE Main FOR Scene::SceneMetamodel»
«FILE (name == null ? "SceneModel" : name) + ".star"-»
<?xml version="1.0" encoding="UTF-8" ?>
<Star version="1.1.1">
	<models_library> 
		«FOREACH models AS model-»
		
			«EXPAND parseModel FOREACH models»
		
		«ENDFOREACH-»
	</models_library>
</Star>
«ENDFILE»
«ENDDEFINE»

«DEFINE parseModel FOR Star::StarMetamodel»
«FOREACH abc.abcs AS def-»
			...
			...
			...
			«ENDFOREACH-»
«ENDDEFINE»

and this is my mwe:

<?xml version="1.0"?>
<workflow>
	<property name="model" value="platform:/resource/star.metamodel/instances/default.scene_model"/>
	<property name="out" value="out" />
	<!-- set up EMF for standalone execution --> 
	<bean class="org.eclipse.emf.mwe.utils.StandaloneSetup">
	<platformUri value="../" /> </bean>
	<component class="org.eclipse.emf.mwe.utils.Reader">
		<uri value="${model}" />
		<modelSlot value="model" />
	</component>
<!-- generate code --> 
<component class="org.eclipse.xpand2.Generator">
<metaModel id="mm" class="org.eclipse.xtend.typesystem.emf.EmfRegistryMetaModel"/>
<expand value="templates::scene2xml::Main FOR model" />
<outlet path="${out}"/> </component>
</workflow>

Finally I report the error:

...

GRAVE: Error in Component  of type org.eclipse.xpand2.Generator: 
	EvaluationException : No Definition 'parseModel for Star::StarMetamodel' found!
	templates::scene2xml.xpt[277,32] on line 12 'EXPAND paeseModel FOREACH models'
	[23,43] on line 1 'EXPAND templates::scene2xml::Main FOR model'               

...

Can someone help me??
Thanks,
Luca

hi,

the error message is

EvaluationException : No Definition 'paeseModel for Star::StarMetamodel' found!

seems you have somewhere a typo.

Hi,

thanks for your answer.
I found the error that you mentioned and I fixed it but it isn't the real problem.

Anyway, now I can execute the script. I've modified the .mwe in the following way and now it works:

<workflow>
	<property name="model" value="platform:/resource/star.metamodel/instances/default.scene_model"/>
	<property name="out" value="out" />
	<!-- set up EMF for standalone execution --> 
	<bean class="org.eclipse.emf.mwe.utils.StandaloneSetup">
		<platformUri value="../" />
		<registerGeneratedEPackage value="Star.StarPackage" />
		<registerGeneratedEPackage value="Scene.ScenePackage" />
	</bean>
	<component class="org.eclipse.emf.mwe.utils.Reader">
		<uri value="${model}" />
		<modelSlot value="model" />
	</component>
	<!-- generate code --> 
	<component class="org.eclipse.xpand2.Generator">
		<metaModel id="mm1" class="org.eclipse.xtend.typesystem.emf.EmfRegistryMetaModel">
		</metaModel>
		<expand value="templates::scene2xml::Main FOR model" />
		<outlet path="${out}"/>
	</component>
</workflow>
