Showing validation error at the right eStructural feature [message #1202968]

Hello,

I am facing a problem while showing a validation error in my xText editor.

My xcore model looks like this:

class Application
{
String name
contains User[] users
}

class User
{
String name
String address
}

My xText grammar looks as below:

Application:
"system" name=ID
users+=User*
;

User:
"userName" userName=ID "{"
"address" address=STRING
"}"
;

I have a java validation method which looks as below:

@Check
public void testApplication(Application app){
//other code
for(User user :app.getUsers()){
//validation goes here
error("Error!!!", user.eClass().getEStructuralFeature(UserPackage.USER_NAME));
}
}

I need to show a validation error at the EStructural Feature, 'userName' in my editor. I am not able to show validation error at the right place.
I throws runtime exception : "The sources EClass 'Application' does not expose the feature 'User.userName'". I can show error at the right place if I pass 'User' as the parameter for my validation method.
But, for some reason, I take 'Application' as the parameter for my validation method.

Can anyone help me by suggesting how I can resolve this?

Thanks in advance Smile
