marc persuy (marc.persuy@wanadoo.fr) reports a bug with a severity of 2
The lower the number the more severe it is.
Short Description
rewrite rules on update or insert do not report errors
Long Description
If you try to use rules to implement update and insert on views, these
rules do not report any error neither on insert nor on update action.
therefore, they are far less usefull.
Sample Code
for instance:
here is a sample table to store customers or suppliers reference.
table is shared by many users, each one having his/her own datas, defined by a view: tiers
the tiers view shows all datas from user and his/her partners, is supposed to allow update of his/her
own datas.
regrettably enough, when you try to update the tiers view, you never get any error, even
if you try to insert a record with an already existing primary key, or any undoable or forbidden operation.
