Hi,

when i use XXEcorePostProcessor i can manipulate my generated metamodel but on my

grammer i use imported metamodel too and i want to change this metamodel too

so how can i done this ?

Sample;

I have User class on a.ecore

and i have Principle Class on b.ecore

and i have Group Class on b.ecore

and i need to do grammer as;

Principle returns Principle:
	Group | a::User

Group:
	'Group'
	name=QualifiedName
	'{'
		('users' '(' users+=[a::User|QualifiedName] ( "," users+=[a::User|QualifiedName])* ')' )?
	'}'
;

but xtext give me error on Principle rule, so i want to change a.ecore and i must User superClass to Principle class. But i cant because 2 ecores on seperated Project and when i give dependiencies to eachother i get cycled dependiency error. (i already have one dependency)

So how can i fix this ? Anyone can help me ?

Regards
