M2T Xpand with existing ecore model - import

Question

I have an ecore model MyModel.ecore for which i want to generate code using Xpand. I dont have edit code or a runtime environment for the xpand project, i just want to create a xpand project, load MyModel.ecore, create a model.xmi using "create dynamic instance" and run.
The problem is that my workflow file doesnt seems to recognize the elements from my metamodel.
Here is the code from my workflow:
<?xml version="1.0"?>
<workflow>
<property name="model" value="com.example/src/Application.xmi" />
<property name="src-gen" value="src-gen" />
<!-- set up EMF for standalone execution -->
<bean class="org.eclipse.emf.mwe.utils.StandaloneSetup" >
<platformUri value=".."/>
</bean>
<!-- instantiate metamodel -->
<bean id="mm_emf" class="org.eclipse.xtend.typesystem.emf.EmfRegistryMetaModel"/>
<!-- load model and store it in slot 'model' -->
<component class="org.eclipse.emf.mwe.utils.Reader">
<uri value="platform:/resource/${model}" />
<modelSlot value="model" />
</component>
<!-- check model -->
<component class="org.eclipse.xtend.check.CheckComponent">
<metaModel idRef="mm_emf"/>
<checkFile value="metamodel::Checks" />
<emfAllChildrenSlot value="model" />
</component>
<!-- generate code -->
<component class="org.eclipse.xpand2.Generator">
<metaModel idRef="mm_emf"/>
<expand
value="template::Template::Root FOR Application" />
<outlet path="${src-gen}" >
<postprocessor class="org.eclipse.xpand2.output.JavaBeautifier" />
</outlet>
</component>
My template file:
«IMPORT MyModel»
«DEFINE Root FOR Application»
«FILE "AndroidManifest.xml"»
«ENDFILE»
«EXPAND ProcesaScreens FOREACH Screens»
«ENDDEFINE»
«DEFINE ProcesaScreens FOR Screen»
«FILE this.name +".java"»
«IF (this.metaType.compareTo(StartScreen.metaType) == 0)»
«EXPAND ProcesaStartScreen FOR (StartScreen)this»
«ENDIF»
«ENDFILE»
«ENDDEFINE»
«DEFINE ProcesaStartScreen FOR StartScreen»
«FILE "FilePrueba.java"»
«ENDFILE»
«ENDDEFINE»
And im getting this error:
695 INFO CompositeComponent - Reader: Loading model from platform:/resource/guiamovil.xpand/src/Application.xmi
890 INFO CompositeComponent - CheckComponent: slot model check file(s): metamodel::Checks
1329 INFO CompositeComponent - Generator: generating 'template::Template::Root FOR Application' => src-gen

1341 ERROR WorkflowEngine - [ERROR]: Couldn't find type or property 'Application'(Element: EXPAND template::Template::Root FOR Application; Reported by: Generator: generating 'template::Template::Root FOR Application' => src-gen)
I imagine its something in the workflow.
Thanks

I think you should register your models first :
<bean class="org.eclipse.emf.mwe.utils.StandaloneSetup" >
<platformUri value=".."/>
<registerGeneratedEPackage value="com.issamux.example"/>
....
//
</bean>
<!-- instantiate metamodel -->
<bean id="mm_emf" class="org.eclipse.xtend.typesystem.emf.EmfRegistryMetaModel"/>
//your code
let me now if this resolved your problem...
