Application: gvSIG desktop

This is a very annoying behavior for the users. Related to #4010

Steps to reproduce:

1. Create a postgis layer like:

CREATE TABLE foo (
  gid SERIAL primary key,
  name text NOT NULL,
  geom geometry(point, 4326)
);

2. Load the layer in gvsig

3. Open edition and insert a point (do not insert alphanumeric data)

4. Close edition, saving

The layer is still in edition mode, and no error is shown to the user. Neither a pop-up, neither in the status bar. The log shows the correct error:

org.gvsig.vectorediting.lib.api.exceptions.EndEditingException: An error has been produced ending edition.
