We try to read data
from a WFS (see attached FME workspace) and get
the following error messages:



xfMap registered 168 messages of type:
'xml-multi-area' Geometry Builder: No geometry was created in the
'xml-multi-area' builder

xfMap registered 168 messages of type: Error
constructing geometry for feature, the feature will be tagged with the
xml_geom_error boolean attribute




    What is
    the reason why the FME-internal 'xml-multi-area'
    Geometry Builder doesn't create area
    geometries in some cases (here: 168 out of 2000) even though all the read
    geometries from the WFS pass all checks of the GeometryValidator (except one
    case with self-intersection).




    Thank you very much in
    advance for your help.

    Hi @pramisters

    I believe FME creates geometries for all passed features. When you run the workspace, you will see 1999 features going to the passed port of the GeometryValidator and 1 feature going to the failed port. In addition, if you attach an Inspector to the passed port, you would see 1999 features within Data Inspector. I would guess that 168 messages refer to elements of the single failed feature (possibly vertices?) and not 168 features out of 2000.

    Kind regards,

    Hi @DebbiAtSafe

     

     

    Thanks for your feeback!

     

    I found out that for the ?168 features the WFS doesn't supply a geometry. So FME is right when it says that it can't create a geometry for these features.

     

    Somehow misleading is the fact that these features pass the GeometryValidator although they have no geometry.

     

    Best regards,
