You're right, stylization of the layer will stop. I can add a try-catch
in there, it should only skip the feature not the whole layer.

In that case stylizing will be interupted and no other geometry will be
displayed?

GetGeometry() is supposed to throw an exception in the case of a null
geometry. In general FDO is exception based and not return code based.
Same for GetString().

Hi,

 

As I am seeing in MapGuide OS when it is reading
FdoIFeatureReader::GetGeometry it is not cheking if NULL pointer is
returned.

 

I would appreciate if someone would comment on this is this a bug or
supposed to be.

 

Can the reader return NULL?

 

 

There is a function IsNull in the reader but that could be two different
situations, like column is not NULL but geometry is not valid.
