Hi

I am getting the following error when I try to save CommodityGroup. There are different hbm files for Commodity, CommodityGroup etc. and error is causing due to the Commodity hbm file.

Error is as follows:

[4/15/04 13:46:39:811 EDT] 7c066763 Configuration I net.sf.hibernate.cfg.Configuration processing one-to-many association mappings
[4/15/04 13:46:39:811 EDT] 7c066763 Binder I net.sf.hibernate.cfg.Binder Mapping collection: com.bunge.bgm.commodity.domain.Commodity.countriesOfOrigin -> Commodity_Country_of_Origin
[4/15/04 13:46:39:841 EDT] 7c066763 SystemErr R java.lang.NullPointerException

I am tring to save CommodityGroup and not the Commodity. But Commodity.hbm is causing a problem because of bag entry. Here are the contents of hbm file:

Commodity.hbm.xml

When bag entries are commented, program works fine and record is inserted into a database. But it gives aboe exception when bag is uncommented.

As mentioned above, I am trying to save CommodityGroup and not Commodity. Also here are the contents of CommodityGroup.hbm.xml:
