Hi,
I am having an issue with a "Collection" not loading.
I am using lazy="false" in my hibernate mapping file.

One thing I have noticed is that if I use the ".get" method using the key object, the collecion does not load. However, if I find the row of data using a simple HQL query then the collection does load successfully.

I have tried using "Hibernate.initialize(...).
Not luck.

Any suggestions/ideas would be greatly appreciated !

I am using Hibernate 3.1.3

I found placing default-lazy="false" in the <hibernate-mapping> file, then my collections would be loaded. When I placed it in the <class> tag like you did, it did not load my collections. I am not exactly sure why.

Hi huangjd,

I tried your suggestion, but no luck. The collection is not initialized. I have created a a method in my DAO that finds the database row using the primary key

i.e. query.uniqueResult();

This works perfectly. I am curious why the get/load methods do not work.
