Hello,
I wish to generate a count of points within Polygons [PointOnAreaOverlayer] but I am unable to generate a count for some polygons because of fme_rejection_code: INVALID_POLYGON_GEOMETRY_TYPE
These Polygons are either Self Intersecting or Multi Polygons. I believe I need to resolve this before I can start counting points inside but Aggregator and Geometry Validator do not seem to fix the issue.
Thanks.

The problem with setting Aggregate Handling to Deaggregate is that it then produces too many polygons and I don't know how to merge them back again to the same input amount.
I added another Aggregator after PointOnAreaOverlayer which has helped a little but still a few too many.
There will be some polygons that have 0 Overlaps but I need to include them also.
You should be able to aggregate back after the point on area overlayer, it looks like you can group by the original OBJECTID and select _overlaps under Attributes to Sum
+44The PointOnAreaOverlayer does not accept aggregate polygons, you will need to deaggregate them - this can be done within the transformer by setting Aggregate Handling to Deaggregate. You will then need to combine totals from each part of the aggregated polygon to get a total

I think the main issue with the Aggregator following on from PointOnAreaOverlayer was that I had selected all of the fields to 'group by' instead of just selecting OBJECTID.
