Yes, you are correct and I have changed the operator ">" . But I am
getting some other error now.

Hi Niyas,
This is something I faced yesterday but did not had the time to work
on it yet. Basically, 2 problems:
1. Error message is crap... we need to improve that.
2. It should not be raising any error. The error means you have a String
attribute you are trying to compare using operators like >, <, >=, <=.
Example:
Person( name > 'Edson' )
And I think the above should work but is not working. I will open a
JIRA for that.
Meanwhile, if you need to have such constraint, a workaround is to
use a predicate:
Person( $n : name, ( $n.compareTo( 'Edson' ) > 0 ) )
