Hi,
I've got an issue where my child entities aren't getting loaded (but save/update is working).
Here's a quick synopsis of my objects:
Code:
[Cart] --one-to-many--> [LineItem] --one-to-one--> [CartItem]
[CartItem] has joined-subclasses [CartCatalogItem] and [CartPunchOutItem].
The one-to-many between Cart and LineItem have cascade="all-delete-orphan" and the one-to-one between LineItem and CartItem have cascade="all".
The save() works just fine, but when I do a load() on Cart, I get the LineItems, but the CartItem in each LineItem is null.
Doen anyone have any ideas what would cause this?
The mappings looks like this:
Code:
<class
name="com.foo.Cart"
table="carts_cart"
dynamic-update="false"
dynamic-insert="false"
>
<id
name="id"
column="cart_id"
type="string"
unsaved-value="null"
>
<generator class="uuid.hex"/>
</id>
<SNIP> .. cart properties .. </SNIP>
<list
name="lines"
lazy="false"
inverse="false"
cascade="all-delete-orphan"
table="carts_line_item"
>
<key
column="cart_id"
/>
<index
column="li_seq"
/>
<one-to-many class="com.foo.LineItem"/>
</list>
</class>
==========================================
<class
name="com.foo.LineItem"
table="carts_line_item"
dynamic-update="false"
dynamic-insert="false"
>
<id
name="id"
column="li_id"
type="long"
unsaved-value="-1"
>
<generator class="seqhilo">
<param name="sequence">carts_line_ids</param>
<param name="max_lo">99</param>
</generator>
</id>
<one-to-one
name="item"
class="com.foo.CartItem"
cascade="all"
outer-join="auto"
constrained="false"
/>
<SNIP> .. line item properties .. </SNIP>
</class>
==========================================
<class
name="com.foo.CartItem"
table="carts_item"
dynamic-update="false"
dynamic-insert="false"
>
<id
name="id"
column="li_id"
type="long"
unsaved-value="any"
>
<generator class="seqhilo">
<param name="sequence">carts_item_ids</param>
<param name="max_lo">99</param>
</generator>
</id>
<SNIP> .. item properties .. </SNIP>
<joined-subclass name="com.foo.CartPunchOutItem" table="carts_po_item">
<key column="li_id"/>
<SNIP> .. punch-out item properties .. </SNIP>
</joined-subclass>
<joined-subclass name="com.foo.CartCatalogItem" table="carts_cat_item">
<key column="li_id"/>
<SNIP> .. catalog item properties .. </SNIP>
</joined-subclass>
</class>
I can see from Hibernate's logging that it is doing a valid query with left-outer-joins to get the CartItem (CartCatalogItem/CartPunchOutItem) data, yet the object isn't populated...
help appreciated.
