In a table T1 a column t2_id is a foreign key to the row id of a
table T2. It is permitted to have null value in this column.
The relationship is correctly managed by Cayenne : in the java
code I can get and set non null values for the column but when I try
to set null value the program itself behaves as expected but the table
in the MySQL database is not updated.
I've checked that :
- the commit() method is called.
- the modeler shows that the attribute is not mandatory.
