The Aggregator has default values set apart from grouping the 4 polygons by an attribute.

Aggregator producing bad geometry
I have a problem with the Aggregator transformer producing invalid geometry. A shapefile with 4 polygons is initially passing through a Geometry Validator (all tests) and are all passing. An Aggregator transformer is then used to merge them and an identical Geometry Validator after this is finding un-repairable self-intersections in the geometry and therefore failing my workspace. Has anybody had this issue before?

Hi,
Probably the polygons are overlapped each other. If you allow that, uncheck OGC issues of the GeometryValidator. Otherwise, you may have to fix the polygons not to overlap.
