[Components4oaw-discussion] Problems with profiled model transformations in MWE

[David C. <dav...@gm...>]

Hi!

I have some problems with some profile transformations between EA and
MDT-UML. Until now I've been working with ea_uml2exporter without
problem, but I'm facing a problem I think I can't manage alone. The
main references I've found are the docs located in SF download section
[1], mainly "Installation_of_oAW_4.3.1_and_EA.pdf",
"EA_and_oAW_Tutorial_1_v1.1.pdf" (both of them are quiet outdated),
and the example workflows provided in ea_uml2exporter-2.0-RC3 bundle.

Right now I'm trying to transform a model with an UML profile, so I'm
working with the example "MyDSL" and replicating the steps described
in the "EA and oAW" tutorial with an ea_uml2exporter-2.0-RC3/MWE based
environment, but I'm having some problems. For example, I created a
workflow for the profile transformation like this:

<?xml version="1.0" encoding="UTF-8"?>
<workflow>
	<property file="profile.properties" />
	<bean class="org.eclipse.emf.mwe.utils.StandaloneSetup" platformUri=".."/>
	<bean class="org.eclipse.xtend.typesystem.uml2.Setup"
standardUML2Setup="true" />

	<component class="net.cmp4oaw.uml2export.mwe.EA_Xmi2ProfileExporter" >
		<EapFile value="${profile.eap_file}" />
		<ModelFile value="${profile.dir}/${profile.name}.profile.uml" />
		<PackageName value="${profile.package}" />
		<Cleanup value="true" />
	</component>
</workflow>

And it results in an apparently MDT-UML correct model. Then I use that
model in the EAP file transformation, but the new resulting model
isn't profiled. The same example works smoothly in
ea_uml2exporter-1.7.2-RC1, but using oAW instead of MWE. I don't know
where is the error, but I wouldn't be surprised if there is an error
in my workflow definitions.

My contents of my workflow.mwe file are:

<?xml version="1.0" encoding="ISO-8859-1"?>
<workflow>
	<property file="workflow.properties" />
	<bean class="org.eclipse.emf.mwe.utils.StandaloneSetup" platformUri=".."/>
	<bean class="org.eclipse.xtend.typesystem.uml2.Setup"
standardUML2Setup="true" />

	<!-- Metamodel-Definition -->
	<bean id="EmfMM" class="org.eclipse.xtend.typesystem.emf.EmfMetaModel"
		metaModelPackage ="org.eclipse.emf.ecore.EcorePackage"/>
	<bean id="UmlMM" class="org.eclipse.xtend.typesystem.uml2.UML2MetaModel"/>
	<bean id="MyDSLMM"
class="org.eclipse.xtend.typesystem.uml2.profile.ProfileMetaModel">
		<profile value="Profile/MyDSL.profile.uml" />
	</bean>
	
	<cartridge file="UML2Export.mwe" inheritAll="true">
		<UML2Exporter.file value="Model/EA_Tutorial1.eap" />
		<UML2Exporter.package value="Models/Project Model/ExamplePkg" />
		<model.dir value="Model/" />
		<model.file value="tutorial.uml" />
	</cartridge>
</workflow>

And the corresponding Uml2Export.mwe file:

<?xml version="1.0" encoding="ISO-8859-1"?>
<workflow>
	<bean class="org.eclipse.emf.mwe.utils.StandaloneSetup" platformUri=".."/>	
	<bean class="org.eclipse.xtend.typesystem.uml2.Setup"
standardUML2Setup="true" />

	<property name="UML2Exporter.Cleanup" value="true" />
	<property name="UML2Exporter.ChangedOnly" value="flase" />
	<property name="UML2Exporter.profilepackage" value="" />
	<property name="UML2Exporter.convertUMLTypes" value="true" />
		
	<component class="net.cmp4oaw.uml2export.mwe.EA_Xmi2Exporter" >
		<EapFile value="Model/EA_Tutorial1.eap" />
		<ModelFile value="${model.dir}${model.file}" />
		<PackageName value="${UML2Exporter.package}" />	
		<Profile value="${profile.file}" />
		<PackageProfile name="${UML2Exporter.profilepackage}"
value="${profile.name}" />
		<ChangedOnly value="${UML2Exporter.ChangedOnly}" />
		<convertUMLTypes value="${UML2Exporter.convertUMLTypes}" />
		<Cleanup value="${UML2Exporter.Cleanup}"/>
	</component>
</workflow>

I've tried too with ea_uml2exporter-2.0-RC2 and it throws the
following error in console:

10030 ERROR WorkflowRunner     - [ERROR]: Error in loading profile
[Profile/MyDSL.profile.uml]. java.lang.NullPointerException(Element:
-UNKNOWN-; Reported by: -UNKNOWN-)

I really don't know where the error is, or if it's a bug in
ea_uml2exporter-2.0-RC3, an error in the definition of my workflows,
etc. I would be very grateful if you could point me to my error.

Thank you very much for your attention :-)
