yurloc opened a new issue, #5945:
URL: https://github.com/apache/incubator-kie-drools/issues/5945
## Parent issue
- #5678
## Failing tests
-
`org.drools.mvel.integrationtests.EdgeCaseNonExecModelTest#testNamedConsequencesInsideOR1`
-
`org.drools.mvel.integrationtests.EdgeCaseNonExecModelTest#testNamedConsequencesInsideOR2`
## Notes
The new parser creates a slightly more flat descr structure compared to the
old parser. I think that's the cause of the later compilation error.
### Old parser output (expected)
```
lhs : [AND [[OR [[AND [[Pattern: id=$a; objectType=Cheese], do[t1]] ],
[Pattern: id=$b; objectType=Cheese]] ], [Pattern: id=$c; objectType=Cheese]] ]
- 0 : [OR [[AND [[Pattern: id=$a; objectType=Cheese], do[t1]] ],
[Pattern: id=$b; objectType=Cheese]] ]
- 1 :
[Pattern: id=$c; objectType=Cheese]
```
Note that the first pattern `$a : Cheese()` and its consequence `t1` are
AND-connected `($a AND t1) OR $b`.
### New parser output (actual)
```
lhs : [AND [[OR [[Pattern: id=$a; objectType=Cheese], do[t1], [Pattern:
id=$b; objectType=Cheese]] ], [Pattern: id=$c; objectType=Cheese]] ]
- 0 : [OR [[Pattern: id=$a; objectType=Cheese], do[t1], [Pattern:
id=$b; objectType=Cheese]] ]
- 1 :
[Pattern: id=$c; objectType=Cheese]
```
Flat OR structure connecting three elements (`$a OR t1 OR $b`).
## Rule code snippet
```
rule R1 when
( $a: Cheese ( type == "stilton" ) do[t1] or $b: Cheese ( type ==
"gorgonzola" ) )
$c: Cheese ( type == "cheddar" )
then
results.add( $c.getType() );
then[t1]
results.add( $a.getType() );
end
```
## Error output
```
