Where can I find an example of invoking a .chk file through the CheckComponent from an MWE2 workflow?

Afaik, that hasn't changed from earlier versions, of course apart from the MWE2 syntax. It would quite probably look something very much like this:

	component = org.eclipse.xtend.check.CheckComponent {
		checkFile = "blah"	// without .chk
		metaModel = org.eclipse.xtend.typesystem.emf.EmfRegistryMetaModel {}
		emfAllChildrenSlot = "modelSlot"
	}

Thank you Meinte, your hint got me started!

The following works fine in the xtext hello world example project:

In the mwe2 file:

component = org.eclipse.xtend.check.CheckComponent {
checkFile = "templates::NewCheckFile"
metaModel = org.eclipse.xtend.type.impl.java.JavaBeansMetaModel {}
metaModel = org.eclipse.xtend.typesystem.emf.EmfRegistryMetaModel {}
expression = "greetings"
}

In the .chk file:

import org::xtext::example::mydsl::myDsl;

context Greeting WARNING "You can't greet the whole world unless you're a spammer" :
name != "world";
