Regression: parser rebuts multiple bindings in constraint conjunction and disjunction
-------------------------------------------------------------------------------------
Key: JBRULES-3025
URL: https://issues.jboss.org/browse/JBRULES-3025
Project: Drools
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: drools-compiler (expert)
Affects Versions: 5.2.0.M2
Reporter: Wolfgang Laun
Assignee: Mark Proctor
Priority: Blocker
Fix For: 5.2.0.CR1
The DRL given below compiled in 5.1.1 and executed as expected, i.e., both rules fired,
producing
or R=1x2
and R=1x2
Now, a syntax error is flagged at the position of the 2nd binding ($w:). Moreover, the DRL
parser is thrown off-track and crashes with sn EmptyStackException as soon as more rules
follow.
package binding;
declare Rect
length : int
width : int
end
rule insert
salience 100
when
then
Rect r = new Rect();
r.setLength( 1 );
r.setWidth( 2 );
insert( r );
end
rule "binding and"
when
$r: Rect( $l: length == 1 && $w: width == 2 )
then
System.out.println( "and R=" + $l + "x" + $w );
end
rule "binding or"
when
$r: Rect( $l: length == 1 || $w: width == 1 )
then
System.out.println( "or R=" + $l + "x" + $w );
end
