I use the Aggregator to merge polygons based on one attribute.
I want to force multipolygons instead of GeometryCollection. When I use GeometryCoercer, nothing is coerced.
Thanks a lot for your help :-)
+22You could try this:
Use AttributeCreator to create the attribute geopackage_type with value wkb_geometry_collection.
That would tell the geoackage writer the geometry is "2D Feature with multiple geometries".
See this link for documentation.

I tried to create the attribute geopackage_type with values wkb_geometry_collection and also wkb_multi_polygon. The new attribute is created but the GeometryCoercer can't export anything:
I get a lot of warnings messages from GeometryCoercer, like "Cannot coerce from IFMEPolygon to fme_multi" or "Cannot coerce from IFMEMultiArea to fme_multi".
If I remove the GeometryCoercer, the 8 multipolygons are exported in my Geopackage but they are GeometryCollection and not multipolygons.
Thanks for your help :-)
If you need to transform a homogeneous aggregate (IFMEAggregate) consisting of only polygons (IFMEPolygon) to a multiarea (IFMEMultiArea), you can just use the GeometryRefiner.
