I am new to xtend and I have started with simple transformation by renaming a class. I have following xtend code for the transformation.

import uml;

uml::Model root(uml::Model m):
	
	let c=m.eAllContents.typeSelect(Class).selectFirst(e|e.name== "A"):
	renameClass(c)->m; 

Class renameClass(uml::Class c1):
	c1.setName("myNewClass");

but I am getting following error:

Hi!

This is most likely a misconfiguration of your Generator component in the MWE workflow. The ProfileMetaModel must be registered first in the list of metamodel contributors to Xpand's Generator component. Since it is delegating to the EmfRegistryMetaModel itself there is no need to add this metamodel also. If you don't work with a profile, you would use the UML2MetaModel in the same way.

Kind regards,
~Karsten
