[Qgis-user] Editing a Postgis view

[Andrea Peri]

Hi Carlo.
Thx for response.

I 'm testing better.
But the strange is that the first write was regulrly executed.
If the view was really read-only it should refuse also the first write.

Instead only from the second write I have the error.

And the qgis don't report me a "readonly view.
But instead a "id primary key cannot be nul" constraint violation.

I try to understand better all of this.

Regards,

A.
