Possibly the polygons are multi-part polygons having just one part.
Check the number of parts with the PartCounter.You can then transform the one-part aggregate polygons into "real" single-part (non-aggregate) polygons with the Deaggregator.

Takashi,

I have problem with this.All features go on aggregate port.

For making this GML file I aggregate polygons based on one attribute to create multies.But just few of them are multies for real.Why does all features go on aggregate port if they are single polygons?

Thanks in advance!

Hi,

Consider using the AggregateFilter to separate single-part polygons and multi-part polygons, and also the HoleCounter+Tester to filter polygons having hole(s).
