Hi,
I'm trying automatically generate my DB schema from my mappings using a XDoclet->.hbm.xml->schema pattern, but SchemaExport crashes with a NullPointerException when lists are included in the mapping.
The fragment that seems to cause it looks like this:
Code:
<list
name="groups"
table="group_map"
lazy="true"
inverse="false"
cascade="none"
>
<key
column="member_id"
/>
<many-to-many
class="com.brokerunity.model.Group"
column="group_id"
outer-join="auto"
/>
</list>
This causes the following error:
Code:
java.lang.NullPointerException

Can anybody shed any light on this?
Thanks.
