Where does it now fail?
I'd assume the first part of the test (where only 1 Cheese exists) would
still pass, but the second part of the test where 3 Cheeses existing in
total to now fail.
Is my understanding correct?
Cheers,
Mike

Previously ALL collections where cloned when bound:
public Object getNonShadowedValue(InternalWorkingMemory workingMemory,
final Object object) {
Object result = this.readAccessor.getValue( workingMemory,
object );
if ( this.isInternalFact() && result instanceof Collection ) {
try {
Collection newCol = (Collection) result.getClass().newInstance();
for ( Iterator it = ((Collection) result).iterator(); it.hasNext(); ) {
Object element = it.next();
newCol.add( element );
}
return newCol;
} catch ( InstantiationException e ) {
// nothing we can do, so just return the resulting object }
catch ( IllegalAccessException e ) {
// TODO Auto-generated catch block }
}
return result;
}
This was left over from shadow facts and actually still existed today. I
have removed the code but now we have a failing test in
FirstOrderLogicTest.testCollectResultConstraints.
rule "Collect Test" salience 70
when
$cheeseList : ArrayList(size == 1) from collect( Cheese( ) );
then
results.add($cheeseList);
end
The reason why this passed before was the collection was cloned, so the
accumulate's evaulations would not impact it. Now it is no longer cloned and
while the rule does not fire the Collection is updated. I think the later is
the correct behaviour and I've updated the test as expected. Everyone
agreed?
