unidirectional reflexive association, problem with "unique"
-----------------------------------------------------------
Key: NETCART-2
URL: http://jira.andromda.org/browse/NETCART-2
Project: .NET Cartridges
Type: Bug
Environment: A n d r o M D A - 3.2-RC1-20060125041715
Reporter: EricR
Assigned to: Naresh Bhatia
I have an unidirectional reflexive association 1-to-(0..1). the association end
got the rolename "previous" and is navigable.
the generated mapping file contains :
<many-to-one name="Previous" class="nGEFHib.Domain.MyClassImpl, nGEFHibCore"
foreign-key="MY_CLASS_PREVIOUS_FKC" outer-join="auto">
<column name="PREVIOUS_FK" not-null="false"
sql-type="NUMERIC(19,0)" unique="true"/>
</many-to-one>
The constraint "unique=true" is an error, since null is allowed in the foreign
key and that produces an SQL runtime error.
