    Description

      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?
