Description Matthieu Wipliez CLA 2010-06-15 04:46:50 EDT 
Build Identifier: 20100610-0636

The following code:

import ecore;

EDataType getEcoreDataType(String name) :
    org::eclipse::emf::ecore::EcorePackage::eINSTANCE.getEClassifier(name)
;

is erroneous according to Xtend editor because:

Unknown variable, type or enumeration literal 'org::eclipse::emf::ecore::EcorePackage::eINSTANCE'

even though the code appears to be valid (the transformation runs fine).

Reproducible: Always

Steps to Reproduce:
1. open the attachment in Eclipse 3.6 RC4

Which metamodel-constributors did you configure in your IDE? (Project properties -> Xpand)?

None, I did not even know that this existed :-)
By default only EMF Metamodels are activated, and the problem disappears if I also enable JavaBeans Metamodel.
I did took the code from the Xtext FAQ though, so it might be worth mentioning this there.
