Hi,
Using hibernate 2.1.3, I have a relationship mapped as a <set/>. However, I prefer a <bag/> so I changed the mapping, changed the code to instantiate a net.sf.hibernate.collection.Bag, and re-deployed the application. Now I'm getting LazyInitializationExceptions...
From the mapping:
Code:
<bag
cascade="all"
inverse="true"
lazy="false"
name="billings"
>
<key column="POLIDX" />
<one-to-many class="Billing" />
</bag>
It used to be a <set/>, all I changed in the mapping was to replace the <set/> tag with a <bag/> tag.
Should I have changed more in the mapping?
The exception is:
Code:
