Kymair Wu updated OPENJPA-2429:
-------------------------------
Description:
Following NPE was thrown out when a @OrderBy modified column is being persisted.
{quote}
Caused by: java.lang.NullPointerException
at
org.apache.openjpa.datacache.DataCachePCDataImpl.clearInverseRelationCache(DataCachePCDataImpl.java:179)
at
org.apache.openjpa.datacache.DataCachePCDataImpl.storeField(DataCachePCDataImpl.java:159)
{quote}
I notice that getOrderDeclaration() of FieldMetaData will return null when both
_orders and _orderDec are null, which cause the NPE.
The only place _orders will be set after class initialization seems to be
getOrders()? But getOrders() is not involved for all the FieldMetaData of
"fields[i].getInverseMetaDatas()"
I'm not sure whether this is a OpenJPA issue but whether this NPE should be
handled internally?
Google returns a potential case but no more information found. See
https://issues.apache.org/jira/browse/OPENJPA-2096?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
and

Thanks!
