Re: [drools-user] More Fun with JBoss Rules IDE and JBoss Rules in general
by Edson Tirelli
Ronald,
Special characters in the rule names are replaced by '_' as a class will
be created with that name. So yes, the given names will generate conflicts.
I'm not sure we can do much about it, as transparently generating unique
names may cause silent unexpected problems.
For now, my recommendation would be for you to use a valid character to
differentiate rule names (like prefixing them with numbers or letters, etc).
If you or anyone have any better idea on how to handle such situations, just
suggest and we can analyze the viability of implementing it.

Migration from 3.0.5 to 4.0.0
by Ronald R. DiFrango
Any catches in migrating from 3.0.5 to 4.0.0? Anything special if you have
a JBoss Rules Eclipse project when upgrading?

Subject: More Fun with JBoss Rules IDE and JBoss Rules in general
To: user(a)drools.codehaus.org
All,
I am now getting the following error:
The type Rule_RNR_Qty____RNR_Adjustment_Qty___100__Tolerance_0 is already
defined RtvDecisionEngine/src/rules/com/circuitcity/rtvcrms/rules
rtv.drl line 758 1180017847586 29221
But I do not have this defined twice, well at least not in my mind. Here
are the two rule names that are conflicting:
"RNR Qty == RNR Adjustment Qty : 100% Tolerance"
"RNR Qty >= RNR Adjustment Qty : 100% Tolerance"
So it appears as though the rule names are not taking into account "special"
characters.
Is this to be expected?

Re: [rules-users] JBoss Rules IDE Error on StringEvaluator
by Edson Tirelli
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
