Hei,
so by looking on the JUMP code,
deleting always creates a null geometry:
com.vividsolutions.jump.workbench.ui.GeometryEditor.remove(Geometry g,
Geometry itemToRemove)
calls
com.vividsolutions.jump.workbench.ui.GeometryEditor.createNullGeometry(Class
geometryClass)
so, we could do the change in createNullGeometry() [though I don't
really like the idea here to create an empty GeometryCollection is
Michael did for the other positions] or in
com.vividsolutions.jump.workbench.ui.EditTransaction.proposedGeometriesValid()
by catching null geometries here and not checking them.
or.. of course... both.
any suggestions by you Larry, Michael, Martin?
Probably the second solution is best?
ohh.. @Martin, actually, if that only happens for point geometries
now... what is with the other geometry.isValid operations... why don't
they return an error if null geomtries are created?
