I am using a static factory in my parent object to construct that
object, initialize its children, and then start a task for each of
them to round out their construction (which is mildly computationally
laborious). However, my task is failing to load the children, and I
was hoping to find some insight as to why.
The factory method:
public static DynamicInverse make(User owner, List<Integer>
dynamic, int size) {
DynamicInverse result = new DynamicInverse(owner,dynamic,size);
PersistenceManager pm = PersistenceSource.get();
Transaction tx = pm.currentTransaction();
try {
tx.begin();
result = pm.makePersistent(result);
for (int i=0; i<size; pm.makePersistent(new
VertexInverse(result,BankerOrder.INTEGER.bitmask(i++))));
pm.close();
tx.commit();
} finally {
if (tx.isActive()) { tx.rollback(); result=null; }
}
if (result!=null) {
Queue q = QueueFactory.getDefaultQueue();
for (VertexInverse vi : result.getInverse()) {
q.add(url("/task/inversion").param("key",
KeyFactory.keyToString(vi.getKey())).method(Method.PUT));
}
}
return result;
}
and in the servlet up to where it fails:
public void doPut(HttpServletRequest request, HttpServletResponse
response) throws IOException, ServletException {
PersistenceManager pm = PersistenceSource.get();
VertexInverse vi = pm.getObjectById(VertexInverse.class,
KeyFactory.stringToKey(request.getParameter("key")));
The log is complaining:
Could not retrieve entity of kind VertexInverse with key
VertexInverse(24)
org.datanucleus.exceptions.NucleusObjectNotFoundException: Could not
retrieve entity of kind VertexInverse with key VertexInverse(24)
however, it's passed only after persisting, and I can see the data
just fine in the developer admin view.
