yurloc opened a new issue, #5803:
URL: https://github.com/apache/incubator-kie-drools/issues/5803
## Parent issue
- #5678
## Partially blocked by
- #5723
## Failing tests
- `org.drools.model.codegen.execmodel.GroupByTest`
## Notes
- `STANDARD_FROM_DRL` tests are blocked by #5723.
- `PATTERN_DSL` tests fail because `groupBy` is not supported.
## Rule code snippet
```
groupby($i: Integer() and exists String();
$key : Math.abs($i);
$count : count())
then
```
## Error output
```
