[henshin-dev] issue running Ecore2Genmodel example and question about do

[Eyrak Paen <paen@xxxxxxxxxxxxx>]

Hello,
I am wondering if there are any known issues with the Ecore2Genmodel
example? I can run the other ones, but this one does not seem to run
completely.

I installed Henshin SDK v0.6.0.I201009090000 into a fresh Eclipse 3.6
SR1 (Modeling Tools) environment.

After calling unitApp1.execute() (Ecore2GenmodelTrafo.java:90), the
genModel parameter is null. Then I get the following exception when it
tries to save the genmodel file:

---
Exception in thread "main" java.lang.IllegalArgumentException: The 'no
null' constraint is violated

org.eclipse.emf.henshin.examples.ecore2genmodel.Ecore2GenmodelTrafo.generateEcore2Genmodel(Ecore2GenmodelTrafo.java:113)
	at
org.eclipse.emf.henshin.examples.ecore2genmodel.Ecore2GenmodelTrafo.main(Ecore2GenmodelTrafo.java:172)
---

I am also wondering how Ecore2Genmodel.henshin was developed -- was it
created entirely in the EMF tree editor?

Finally, is there any documentation about the classes in the henshin
metamodel, apart from the articles in the wiki?
