Edson,
Actually, I am glad it caught it, because that was not my intent at all. I
was a global search and replace issue on my part.
If you added in support for these operations, I still think a warning would
be in order because that may not be what you intended,
I am considering the move to 4.0.x series, but I have hard deadline and am
being risk averse at this point.

Ronald,
I see now. Version 3.0.x still used integer codes for operators and
that is the reason the error message is saying operator '50'.
So, the problem is you are trying to use >= (operator 50) with a
string attribute:
public static final int EQUAL = 1;
public static final int NOT_EQUAL = 10;
public static final int LESS = 20;
public static final int LESS_OR_EQUAL = 30;
public static final int GREATER = 40;
public static final int GREATER_OR_EQUAL = 50;
public static final int CONTAINS = 60;
public static final int MATCHES = 70;
public static final int EXCLUDES = 80;
Version 4.0 already uses type safe enums for operators, so message
will be better.
Back to your problem, I guess we should add support for comparisons
between strings using the java lexicographic order. We don't do it as of
today.
What you can do as a work around is to use a predicate:
MyFact( $s: strAttr -> ( $s.compareTo( $otherValue ) >= 0 ) )
May I ask you please to open a JIRA with a feature request to
support comparison for string objects?
Thank you,
Edson
