2023 Week 15-17 (from Apr 10), 2023 Week 18-20 (from May 1), 2023 Week 21-23 (from May 22), 2023 Week 24-26 (from Jun 12)
Issue Description:
This rule:
rule Rule1
when
not String()
List() from collect (Integer() from new Integer [] {1,2})
Boolean() // always false
then
end
rule Rule2
when
not String()
List() from collect (Integer() from new Integer [] {1,2})
then
insert(new String());
end
fails with (just fireAllRules without inserting a fact)

because in the rightTuples in the RIA node, the order of 2 SubnetworkTuple (stagedNext/stagedPrevious) was inverted while rightTuples.inserFirst is not changed. The inversion was caused by previous PhreakFromNode.doLeftDeletes.
This issue happens only with non-exec-model, because exec-model happens not to share the FromNodes. (This may be another issue, but no harm)
Acceptance Criteria:
- Don't throw NPE. Just Rule2 is executed
- clones

- Resolved
