Geography

[Leggio Mario <ma...@telespazio.com>]

Dear all,

I'm using olingo 4.7.1 and I have a Geography property in my entity.


I created a new edm.geo.Geospatial object as:

     Geospatial geospatial = new Polygon(Dimension.GEOGRAPHY, SRID.valueOf("4326"), ..., ...);

If I try to put it into a property defined as:

     new CsdlProperty().setName(F_GEO).setType(EdmPrimitiveTypeKind.GeographyPolygon.getFullQualifiedName()).setNullable(true)

The above code works perfectly when I retrieve the entity.


But If I try to put my geometry into a property defined as generic geography like:

     new CsdlProperty().setName(F_GEO).setType(EdmPrimitiveTypeKind.Geography.getFullQualifiedName()).setNullable(true)

I have an error when serializer tries to convert the object to a string... why?

ERROR - Wrong value for property!
Wrong value for property!

I need to put different geometries int my F_GEO property (It could be a Polygon or a LineString or a MultiPoint and so on...)

Reading documentation, it seems that EdmPrimitiveTypeKind.Geography should be used for all geometry types, isn't it?

Where am I going wrong? Is there a workaround?

I'm looking forward to reading your reply

Regards

           Mario
