Matteo Casalino created DROOLS-4903:
---------------------------------------
Summary: In constraints fail to compile if negated or inside a forall
pattern
Key: DROOLS-4903
URL: https://issues.redhat.com/browse/DROOLS-4903
Project: Drools
Issue Type: Bug
Components: core engine
Affects Versions: 7.31.0.Final
Reporter: Matteo Casalino
Assignee: Mario Fusco
Attachments: in-constraint-negation.tgz
It appears that the KieBuilder fails to compile the following pattern:
{noformat}
Pojo(!(x in (1,2,3)))
{noformat}
returning the following error:
{noformat}
Error Messages:
Message [id=1, kieBase=defaultKieBase, level=ERROR, path=rules.drl, line=4, column=0
text=Unable to Analyse Expression !(x in (1,2,3)):
[Error: unexpected token: ,2]
[Near : {... !(x in (1,2,3)) ....}]
{noformat}
Furthermore, as of Drools 7.29.0.Final, the following form will also fail to compile:
{noformat}
forall(Pojo(y==42, x in (1,2,3)))
{noformat}
with the following error:
{noformat}
Error Messages:
Message [id=1, kieBase=defaultKieBase, level=ERROR, path=rules.drl, line=4, column=0
text=Unable to Analyse Expression !(y==42) || !(x in (1,2,3)):
[Error: unexpected token: ,2]
[Near : {... !(y==42) || !(x in (1,2,3)) ....}]
{noformat}
The latter is likely a consequence of the negation introduced by
[DROOLS-4632|https://issues.redhat.com/browse/DROOLS-4632]
