Unexpected behavior on finding a Composite Key entity with a single value.
--------------------------------------------------------------------------
Key: OPENJPA-365
URL: https://issues.apache.org/jira/browse/OPENJPA-365
Project: OpenJPA
Issue Type: Bug
Components: kernel
Environment: Windows XP, JDK 1.5, OpenJPA 0.9.7
Reporter: Gene Wu
Entity A has a composite key AId, thus User should look up A with an instance
of AId.
Example: em.find(A.class, new AId());
In case of looking up A with a single value, for example: em.find(A.class,
12345). It will through an unexpected exception:
>>>The id type "AId" specfied by persistent type "A" does not have a public
>>>string or class + string constructor.
>>>>> org.apache.openjpa.kernel.BrokerImpl.newObjectId
>>>>> (BrokerImpl.java:1120)
>>>>> [WLServer TmsServer] at
>>>>> org.apache.openjpa.kernel.DelegatingBroker.newObjectId
>>>>> (DelegatingBroker.java:254)
>>>>> [WLServer TmsServer] at
>>>>> org.apache.openjpa.persistence.EntityManagerImpl.find
>>>>> (EntityManagerImpl.java:345)
I suppose to get an exception of error id type.
