Wolfgang,
thanks for having tried this, but following your examples I made some
further tests (on the master branch) end it seems to me that constraints in
the from lowerBound < value < upperBuond are not working at all regardless
of the fact if value is null or not.
For instance I tried
declare Cont
val:Integer
end
rule makeFacts
salience 999999
when
then
insert( new Cont( 2 ) );
end
rule "3 < val < 10"
when
$c: Cont( 3 < val < 10 )
then
System.out.println( drools.getRule().getName() + " fires" );
end
and this last rule fires even if val is set to 2 (while it doesn't if I
rewrite the pattern as: Cont( val > 3 && < 10 ) ). I am just guessing now,
but it seems to me that instead of testing lowerBound < value < upperBuond
it is actually only checking lowerBound < upperBuond because the only way
to avoid that the rule fires is to write a pattern like: Cont( 11 < val < 10
)
Moreover I cannot find any doc stating that we are supporting that format of
constraints, neither any test in our code base using them. Can you confirm
that this constraint format should be supported by Drools? If so I will try
to fix it asap.
Mario
