so please give the solustion

i received the same exception in the following situation:
there are two tables, a and b with a 1:n relation.
if there's an entry in table b with no regarding entry in table a then i get the exception.

more concrete explanantion:

table a (id, text)
1, test1
2, test2

table b (id, fk_table_a, text)
1, 1, something
2, 1, anything
3, 4, everything

as you can see, there's no value 4 in table a although table b has a foreign key to it. that's why it causes an "ObjectNotFoundException: No row with the given identifier exists".

so have a look at your values in the database if there's an object with id 0 (JobAd#0).

i hope this helps.

best regards
patrik

Just adding an info:
if the relation that hasn't been found is not a key, you can add to you mapping:
