Hi,
Has anyone seen this exception before? I traced it into the search code, but not sure what triggers it.

regards.

Code:
java.lang.ClassCastException: java.lang.Long at
org.hibernate.search.bridge.builtin.StringBridge.objectToString(StringBridge.java:16)
org.hibernate.search.bridge.String2FieldBridgeAdaptor.set(String2FieldBridgeAdaptor.java:21)
org.hibernate.search.engine.DocumentBuilder.getDocument(DocumentBuilder.java:395)
org.hibernate.search.engine.DocumentBuilder.addWorkToQueue(DocumentBuilder.java:302)
org.hibernate.search.backend.impl.BatchedQueueingProcessor.performWork(BatchedQueueingProcessor.java:111)
org.hibernate.search.backend.impl.PostTransactionWorkQueueSynchronization.afterCompletion(PostTransactionWorkQueueSynchronization.java:49)
org.hibernate.transaction.JDBCTransaction.notifyLocalSynchsAfterTransactionCompletion(JDBCTransaction.java:243)
org.hibernate.transaction.JDBCTransaction.commit(JDBCTransaction.java:121)
mil.darpa.tn.model.ReportModelFactory.saveReport(ReportModelFactory.java:102)
mil.darpa.tn.model.ReportFactory.saveReport(ReportFactory.java:77)
        at mil.darpa.tn.TNMain.insertReport(TNMain.java:61)
        at mil.darpa.tn.TNMain.main(TNMain.java:73)






In Work.java there is:

Code:
            public Serializable getId() {
                        return id;
            }




Which I confirmed returns a Long.

However, this value is then sent to:

Code:
                                    builder.addWorkToQueue(work.getEntity(), work.getId(), work.getType(), luceneQueue, searchFactory);


in BatchQueuingProcessor, where it eventually gets sent to:

Code:
                                    idBridge.set( idKeywordName, id, doc, Field.Store.YES, Field.Index.UN_TOKENIZED, idBoost );


in DocumentBuilder. idBridge is String2FieldBridgeAdaptor


Code:
            public void set(String name, Object value, Document document, Field.Store store, Field.Index index, Float boost) {

                        String indexedString = stringBridge.objectToString( value );   <---- CCE

Hum interesting,
Pretty much like Hibernate, you will have to specify the actual type needed, because the type is resolved at init time, not at runtime

Annotating your serializable type to @FieldBridge(impl=LongBridge.class) should do the trick.

The weird thing is that an exception should have been raised (Unable to guess FieldBridge).

I have opened a JIRA issue to track it down http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-37

Thank you for the tip. Oddly enough, this field was the required Hibernate Long getId() property.

EDIT: Adding the FieldBridge annotation does not seem to work (for me).

Hey, I tried to reproduce your problem but I could not managed to.
There should be something else not described in the post. If you still have the code around, can you post ti to JIRA.

I'll try to help you with that .. It should be easy .. because I don't seem to have problems with the FieldBridge annotation..
I'll see what I can do.

Cheers

I have the same problem - and I can't figure out where to place the @FiledBridge annotation. Here's my full stack trace:

I'm using the versions recommended in the documentation:

http://www.hibernate.org/hib_docs/searc ... gle/#d0e44

namely

<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-search</artifactId>
<version>3.0.1.GA</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-annotations</artifactId>
<version>3.3.0.ga</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>3.3.1.ga</version>
</dependency>

I run jboss-4.0.3SP1.

PS. the stack trace is from the latest search version - that's why the line is 15 not 16.

Also the $Proxy176.updateTask(Unknown Source) is a EJBLocalObject implementation - I don't known if that's relevant.

Any clues?

Also can somebody direct me to where I can read more about how the search deals with inheritance?
