Hi, I am new to xText - so please bear with me  I am trying to implement a Formatter2 in an xText project generated from an EMF...
Previously I was able to use classes generated from my domain (e.g robot class below) like an EObject - like so...
def dispatch void format(Robot robot, extension IFormattableDocument document) {
// TODO: format HiddenRegions around keywords, attributes, cross references, etc.
robot.regionFor.features(URDFPackage.Literals.NAMED_ELEMENT__NAME).head.append[newLine]
But this is no longer the case. Now I get a compiler error saying that my domain class cannot be converted to EObject...
I have made som small changes to my metamodel - e.g NamedElement class, that all my objects inherit from, has been changed from abstract class to interface...could this be cause?
Also - I would like to create some convenience methods for formatting my content like so - but I having problems finding the correct syntax, so I can use the extension methods on document:
def <T extends EObject> indentKeyword(T construct, String myKeyword, extension IFormattableDocument document) {
construct.regionFor.keyword(myKeyword).prepend[space = Strings.repeat(" ", 6)]
}
Thank you very much in advance

Hi
regarding (1) that should not happen.
can you share a small ecore/xcore file reproducing this?
regarding (2) i dont see where the problem is
def dispatch void format(Model model, extension IFormattableDocument document) {
for (Greeting greetings : model.getGreetings()) {
greetings.format;
greetings.indentKeyword("Hello", document)
}
}
def <T extends EObject> indentKeyword(T construct, String myKeyword, extension IFormattableDocument document) {
construct.regionFor.keyword(myKeyword).prepend[space = Strings.repeat(" ", 6)]
}
