Hello!

Simple question:

I have two tables, table1 and table2.

table1 has one column table2id.

Now I want to create a new entry in table1.

Table1 t1 = new Table1();

Table2 just holds a status:

Table2 t2 = new Table2();
t2.setId(1);

t1.setTable2(t2);

...save...

Well, sometimes this scenario works, sometimes not. In my case it just works for table id 1.
If I set t2 to id 0 i get an exception
not-null property references a null or transient value: ...

How does hibernate check if the object exists ( for database integrity ). I don´t want hibernate
to check if it exists because a) it exists and b) there should be no additional database call for getting
this second object every time.

Thanks a lot!
