    <p>Im trying to use the datastore in google app engine. I'm able to make an object persistent and can retrieve it by id. But I can't query it.</p> <p>This is my entity:</p> <pre><code>package my.company.domain; import javax.jdo.annotations.IdGeneratorStrategy; import javax.jdo.annotations.PersistenceCapable; import javax.jdo.annotations.Persistent; import javax.jdo.annotations.PrimaryKey; @PersistenceCapable(detachable="true") public class User { @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) long key; @Persistent private String name; @Persistent private String password; @Persistent private boolean adminPrivileges; //getters &amp; setters } </code></pre> <p>And my Unit Test:</p> <pre><code>public void persistAndFindUserTest(){ User user = new User(); user.setName(johnDoe"); user.setPassword("password"); UserService userService = new DefaultUserService(); user = userService.createUserInDatabase(user); User userFromPersistence = userService.getUserById(user.getKey()); Assert.assertEquals(user.getName(), userFromPersistence.getName()); Assert.assertNotNull(userService.findUserByName("johnDoe")); } </code></pre> <p>findUserByName is defined als follows:</p> <pre><code>public List&lt;User&gt; findUserByEmail(String email){ PersistenceManager persistenceManager = PMF.get() .getPersistenceManager(); Query q = persistenceManager.newQuery(User.class); q.setFilter("email == emailParam"); q.declareParameters("String emailParam"); q.setUnique(false); List&lt;User&gt; results = null; try { results = (List&lt;User&gt;) q.execute(email); } finally { results = (List&lt;User&gt;)persistenceManager.detachCopyAll(results); q.closeAll(); } return results; } </code></pre> <p>Following Exception occurs (line 116 is where I try to detach the result list):</p> <pre><code>java.lang.NullPointerException at com.google.appengine.datanucleus.query.QueryEntityPKFetchFieldManager.fetchLongField(QueryEntityPKFetchFieldManager.java:74) at org.datanucleus.identity.IdentityUtils.getApplicationIdentityForResultSetRow(IdentityUtils.java:101) at com.google.appengine.datanucleus.EntityUtils.entityToPojo(EntityUtils.java:1009) at com.google.appengine.datanucleus.query.DatastoreQuery$2.apply(DatastoreQuery.java:227) at com.google.appengine.datanucleus.query.DatastoreQuery$2.apply(DatastoreQuery.java:224) at com.google.appengine.datanucleus.query.LazyResult.resolveNext(LazyResult.java:96) at com.google.appengine.datanucleus.query.LazyResult$LazyAbstractListIterator.computeNext(LazyResult.java:229) at com.google.appengine.datanucleus.query.AbstractIterator.tryToComputeNext(AbstractIterator.java:131) at com.google.appengine.datanucleus.query.AbstractIterator.hasNext(AbstractIterator.java:126) at com.google.appengine.datanucleus.query.LazyResult$AbstractListIterator.hasNext(LazyResult.java:183) at org.datanucleus.api.jdo.JDOPersistenceManager.detachCopyAll(JDOPersistenceManager.java:1213) at ch.mttb.clientmanagement.service.impl.DefaultUserService.findUserByEmail(DefaultUserService.java:116) at ch.mttb.clientmanagement.service.test.UserServiceTest.persistUserTest(UserServiceTest.java:44) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:45) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:42) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:20) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:28) at org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:30) at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:263) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:68) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:47) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:231) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:60) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:229) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:50) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:222) at org.junit.runners.ParentRunner.run(ParentRunner.java:300) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:50) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:467) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197) </code></pre> <p>Im using the jars from the GAE SDK 1.7.2, the datanucleus jars are the following:</p> <p>datanucleus-api-jdo-3.1.0-m3.jar datanucleus-api-jpa-3.1.0-m3.jar datanucleus-appengine-2.1.0-final.jar datanucleus-core3.1.0-m5.jar</p> <p>My enhancer.log files still are empty.

COAs anyone can see from public SVN, an NPE at that line makes no sense (i.e there's nothing that can NPE) http://code.google.com/p/datanucleus-appengine/source/browse/branches/2_1_0/src/com/google/appengine/datanucleus/query/QueryEntityPKFetchFieldManager.java#74 Also if you get query results, the first thing I would have done is actually look at them before attempting to do anything with them.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
