Reese, the leads for geomason are away for the holidays so you should expect a slow response on this one. But we'll get to you as soon as we can. If it's taking to long, send me a personal reminder.

The getGeometry method throws a NullPointerException if the MasonGeometry object does not contain any user data. The getGeometry method also throws a ClassCastException if the MasonGeometry object contains user data that is not of type List<AttributeField>. Line 387 and 388. The MasonGeometry object does not require that the userData member be set and does not specify that the userData field have a type of List<AttributeField>. I found this while trying to search the field for a particular MasonGeometry to see if it had been added or not. For my purposes, a search using just the underlying JTS Geometry object would be preferred. Is there any way to make the findGeometry method public? > > Thanks, > > Nathan > >
