aabbcc closed OPENJPA-2138.
---------------------------
Resolution: Cannot Reproduce
> One-To-Many mapping is not working
> ----------------------------------
>
> Key: OPENJPA-2138
> URL: https://issues.apache.org/jira/browse/OPENJPA-2138
> Project: OpenJPA
> Issue Type: Bug
> Components: jpa
> Affects Versions: 2.1.1
> Reporter: aabbcc
>
> I have business object model with below structure
> Class A {
> private B b;
> }
> Class B {
> private String joinKey;
> private List<C> c;
> }
> Class C {
> private String joinKey;
> private String str1;
> private String str2;
> }
> In the ORM.xml,I have specified mapping like this
> <entity class="xxx.xxx.A">
> <table name="table1"/>
> <attributes>
> <one-to-one name="name1" target-entity="xxx.xxx.B">
> <join-column name='"column1"' referenced-column-name='"column1"'/>
> </one-to-one>
> </attributes>
> </entity>
> <entity class="xxx.xxx.B">
> <table name="table2"/>
> <attributes>
> <basic name="joinKey">
> <column name="column1"/>
> </basic>
> <one-to-many name="name1" target-entity="xxx.xxx.C">
> <join-column name='"column1"' referenced-column-name='"column1"'/>
> </one-to-many>
> </attributes>
> </entity>
> <entity class="xxx.xxx.C">
> <attributes>
> <basic name="joinKey">
> <column name="column1"/>
> </basic>
> <basic name="str1">
> <column name="str1Column"/>
> </basic>
> <basic name="str2">
> <column name="str2Column"/>
> </basic>
> </attributes>
> </entity>
> The one-to-many mapping specified in the entity C does not work by both
> approach 1) JoinColumn 2) JoinTable. My code skips this mapping while
> generating SQL query.
> But instead of one-to-many mapping If I specify one-to-one mapping and change
> class B to replace "private List<C> c;" with "private C c;" then the
> one-to-one mapping works fine.
> I am using OPENJpa 2.1.1, as per the documentation one-to-many mapping should
> work but it seems OPENJpa 2.1.1 API is working as expected. It seems there is
> bug in API.
> Can you please advise to fix this issue?
