Hibernate version:2.1.8


I'm using a one-to-one mapping between two tables.

mapping in parent table

<one-to-one
name="child"
class="Child"
outer-join="auto" cascade="all-delete-orphan"
/>

mapping in child

<one-to-one
name="parent"
class="Parent"
outer-join="auto"
constrained="true"
/>

Its throwing an exception when loads the mapping

Error parsing XML: XML InputStream(222) Attribute "cascade" with value "all-delete-orphan" must have a value from the list "none all save-update delete ".

Please help.

do i need to set any thing else to use all-delete-orphan.

My requirement is to delete the child when i set the child as null in parent and save the parent.

Try "all,delete-orphan" instead.

Are you sure you're using v2.1.8 ?

The value "all-delete-orphan" is correct under that version. The cascade values were changed in v3.0.x.

And delete-orphan is for deleting ALL of the children in the event you delete the parent. You know, deleting children that would otherwise be orphaned.


Actually, now that I realize it's a <one-to-one> mapping, you just need to specify cascade="delete" or cascade="all" to ensure the child is deleted.

all-delete-orphan is supported in both HB3 and HB3.

However, there is no support for orphan delete for one-to-one (cannot be implemented).

Thanks for the replies..

If orphan delete is not supported for one-to-one mapping, is there any other work around solution to implement the same..

I tried with "all" option, but its not deleting child table.

even though its a one-to-one map child table, can i map it as "set" and achieve the same?
