Hello eveyone:
    Please help me: I want to use CMP 1:N relationship and have written "abstract Collection getXxx" and "abstract void setXxx(Collection xxx)".
    The getter work well but setter seems never take effect. So I did a experiment that manual insert into database some data to make a relationship(set foreign key directly) and invoked setter immediately following getter like this:
    Collection coll=XXXlocal.getXxx();
    XXXLocal.setXxx(coll);

to my surprise, all relationship I made manually were gone(foreign key in database changed to null).

It's my first time to use CMP 1:N relationship, anyone help to tell me what I am wrong.
