Hi,
I have a task to validate the keyword.
Model:
greetings+=Greeting*;

Greeting:
'Hello' name=STRING '!' ;

I want to display a custom warning message if the input is "hello" saying as "hello should be Hello"

is your grammar case insensitive or is it not.

if not, then allow it in your grammar

'Hello' | 'hello'

in both cases:

either assign the keyword to get the value in the validator

helloKeyword=(....)

or use NodeNodelUtils to retrieve the nodes for the Greeting eobject and then iterate the nodes and find the one whose grammar element is the hello keyword
