Hi,
Thanks. I'll wait for a new nightly build and once it is available I will test
saving with some odd geometry combinations.

Aihe: Re: [JPP-Devel] Saving a layer with empty geometries into
shapefiles
Hi Jukka,
I just improved empty geometry handling in OJ shapefile driver.
Hope it will solve your problem. I had to do many modifications in the
code. I made extensive tests to make sure the code is as robust as before, but
I would be pleased if you could complete with your own tests.

Hi,
JUMP DB Query plugin http://jumpdbqplugin.sourceforge.net/ used
to create a little polygon as a fake geometry for all the lines which the SQL
query was returning without a geometry. Now the new versions of the plugin,
starting from version 0.7.2. are creating an empty geometry as
"GEOMETRYCOLLECTION EMPTY".
This works fine as long as I am working with OpenJUMP and also
saving into JUMP jml format goes OK. But saving into shapefiles gives problems
and I have not discovered how I could keep the important attribute data that I
have also for the features without geometry.
If there are no other geometries on the layer, the OJ message
while doing shapefile save is
java.lang.Exception: Could not determine shapefile type - data
is either all GeometryCollections or empty

Is it possible to save things without geometries into
shapefiles at all? It is easy to generate test data, just create a new layer
and insert a new WKT feature as GEOMETRYCOLLECTION EMPTY and try to save the
layer. Next digitise a point, for example, on the layer, and try saving again.
