OSGeo FDO SpatialCondition Error

[fieldguy]

I am trying to replicate the code >>in this post<<

but I am getting an error >>"The property "SHAPE" is not in the reader's selected property set"<<.

I can connect to my shp file and obtain all of the features but I want to filter by a user selected rectangle.

Does anyone have working code for using a polygon as in "OSGeo.FDO.Filter.SpatialCondition("SHAPE", OSGeo.FDO.Filter.SpatialOperations.SpatialOperations_Inside, gv)?

There are samples in the DevBlog but those are using "layers" attached to the current map - that's not what I want.

If necessary I can obtain all of the "points" in this case, and determine if the points are within the rectangle, but that is a "worst case" scenario.

I got this to work - "Geometry" was the key word.
