Silent exclusion of null-valued map entry ----------------------------------------- Key: HHH-4947 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4947 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.5.0-CR-1, 3.3.2 Reporter: Tsering Shrestha <class name="Product"> <id name="id"> <generator class="native"/> </id> <map name="sellingPrice"> <key column="PRODUCT" not-null="true" foreign-key="FK_SP_PRODUCT"/> <map-key type="string" column="model" not-null="true"/> <element type="double" column="price" not-null="false"/> </map> </class> Product product = new Product(); Product.getSellingPrice().put("XL",null); Product.getSellingPrice().put("L", 34.90); session.save(product) Gives the following SQL: insert into PRODUCT (id) values (null) call identity() insert into SELLINGPRICE (PRODUCT, MODEL, PRICE) values (?, ?, ?) And the SELLINGPRICE table indeed only has one row. Why does Hibernately *silently* remove my null-valued entry? I would either want it to be able to save the entry or raise an exception that it cannot.
