Error in entering an ID having the same name as a keyword [message #1800639]

Hi,

I have created an Xtext grammar language in which I have a keyword named 'Name'. When I try to enter 'Name' as an ID for another rule in runtime, I get an error stating "mismatched input 'Name' expecting RULE_ID".
Could you please let me know whether it is possible to allow entering the same name as a keyword for an ID?

Regards!

You can using a datatype rule. This is explained here

Or you use the out-of-the-box option to prefix a keyword with a "^":

enter "^Name" instead of "Name"

Hi Christian and Uli,

Both of your solutions worked for me. Since I needed the keywords as they are for identifiers, I used Christian's solution.
Thank you both for the support!

Regards!
