I would like to perform a spatial join of points and polygons in FME Workbench by PointOnAreaOverlayer transformer. The result should be a country polygons with additional attributes from points. I have a workspace:

enter image description here

What I have in rejected features, in attribute table column fme_rejection_code: Invalid Polygon Geometry Type:

enter image description here

Do you know how can I repair or change the Invalid Polygon Geometry Type features? I have tried GeometryValidator transformer - without results - all areas were rejected in PointOnAreaOverlayer transformer.

The rejected features are probably aggregates (collections).

You can use a DeAggregator to explode the collections.

Aggregates can either be deaggregated before processing or rejected.

  • Right answer! I had to deaggregate and later aggregate the polygons.

@nielsgerrits answer led me to the solution. In PointOnAreaOverlayer transformer I have to deaggregate features, and later aggregate them by aggregator transformer.
