Validating string list items under a parent object. [message #1271249]

If I have the following definition in my model::

Attribute : (=> name=QualifiedName '[' ']' ) (( '='  (values+=STRING)? (',' values+=STRING)* ';')

Now (for example), if I want to validate all values against a whitelist of values (for example "one", "two", "three").

I'm struggling to find a way to underline the correct item(s), I can only find a way to add an error flag to the parent object (in this case 'Attribute'). This is because the 'error' method within the validation class can only take EObject or EStructuralFeature and when the validation fails, I only have instances of String and the parent class.

Is there a way that I can use the parent class, and the text content or index of a child string within the EList (with name 'values'), and underline the correct item that failed the validation (without changing the type of the values from STRING to some other containing object)?

Hi this works out of the box. There are error methods that accept an
index besides the estructuralfeature

Thank you. A total non-issue. Sorry.
