Description Robert von Massow CLA 2011-04-08 09:01:08 EDT 
Build Identifier: 201104061304

	dispatch generate(AbstractSection aS) {
		'''«aS.title.genPlainText»
		«FOR ss:(aS.subSection as Iterable<AbstractSection>)»
	«ss.generate» 
		«ENDFOR»
		'''
	}
When removing the last tab from the line containing «ss.generate» the reconciler crashes with the following error message:

An internal error occurred during: "XtextReconcilerJob".
