[jboss-jira] [JBoss JIRA] Updated: (JBRULES-954) '==' & '!=' not working properly with globals
[ http://jira.jboss.com/jira/browse/JBRULES-954?page=all ]
Brian Enderle updated JBRULES-954:
----------------------------------
Description:
The equality operators (== & !=) are not working correctly when comparing a value to a
global. This holds true for globals of the type java.lang.Character, java.lang.String and
java.lang.Long (only ones I tested, but probably others as well).
Given:
Person object with sex set to 'M'
rule "Must be male"
when
$p : Person ( sex == 'M' )
then
System.out.println ( "- This is a man" );
end
rule "Cannot be a man"
when
$p : Person ( sex != 'M')
then
System.out.println ( "- This must be a woman")
end
Results:
- This is a man
If we replace the 'M' with the global "maleCode" and set it to
'M' in our calling program then,
gloabl java.lang.Character maleCode;
rule "Must be male"
when
$p : Person ( sex == maleCode )
then
System.out.println ( "- This is a man" );
end
rule "Cannot be a man"
when
$p : Person ( sex != maleCode)
then
System.out.println ( "- This must be a woman")
end
Results:
- This is a man
- This must be a woman
Both rules are passing when one, the latter, should fail
