Hi,

I have a grammar in which a object Attribute reference another object Domain like this

Attribute:
domain= Domain

I use Attribute.getdomain() to get all the information from the domain.

My problem is that when the domain referenced doesn't exists xtext marks it as an error and return an object with all the fields null.

I want to know if there is a way to get the name of the domain that was written in the object Attribute when the domain doesn't actually exists ?.

Thanks.

I think you could try to use NodeUtil.getNodeAdapter(EObject) and evaluate the node at this position.

Kind regards,

Thanks for answering .

I found the name using

EList<LeafNode> list = NodeUtil.getNodeAdapter(attribute).getParserNode().getLeafNo des();

And iterating over the list.
It works but its not very good, since y have to iterate over the list which has a node for every word in the text.

If anyone has a better solution , it good be great.

thanks
