Bug 1021810

- Workaround Description:

The types of the query arguments has to be coherent with the declarations so either rewrite the query signature like:

query isTriple( int $a, int $b, int $c )

or change the patterns in the query itself like:

Integer( this == $a )

- Steps to Reproduce:

Compile and start session from KB.

rule "kickoff"
salience 100
when
then
for( Integer i: new Integer[]
{3,4,5,12,13 }

)
{ insert( i ); }

end

rule "find triple forward"
when
Integer( $a: intValue )
Integer( $b: intValue > $a )
Integer( $c: intValue > $b )
eval( $a*$a + $b*$b == $c*$c )
then
System.out.println( "fwd: " + $a + " " + $b + " " + $c );
end

query isTriple( Integer $a, Integer $b, Integer $c )
Integer( intValue == $a )
Integer( intValue == $b && > $a )
Integer( intValue == $c && > $b )
eval( $a*$a + $b*$b == $c*$c )
end

rule "find triple backward"
when
isTriple( $a, $b, $c; )
then
System.out.println( "bwd: " + $a + " " + $b + " " + $c );
end
