Persistent of same reference twice - hibernate

Question

Hello,
I tried to save an object - (object1) that is contained by 2 different objects (object2 and object3).
first, when i saved object2 - it succeeded and the object was saved (object 2 contains object1)
than, i tried to save object3 (that contains also object1 - the same reference) and it cause
transient object exception.
i also noticed that in the object2 - object1 has id
and in the object3- object1 doesn't have id although object1 is the same reference in both of the objects.
what should i do?
how could i inform object3 that object1 inside of him is already saves and has id..?

Answer 1

I tried to think of a way to reword my SQL so that it would only reference the variable once and I came up with:
select product_name,
       product_type,
       to_date(expiry_date, 'DD/MM/YYYY') expiry_date
  from products
where product_name like nvl(#name, '%')
   and product_code like nvl(#code, '%')I thought I had finally found an answer, but the input xsd generated has errors:
<xs:sequence>
      <xs:element name="name" type="/>
      <xs:element name="type" type="/>
</xs:sequence>It seems like it is trying to make the comma after the variable part of the name. It happens if I try and put the input variable inside any function. Am I missing some obvious syntax issue?
