Entity not reset as null and internal lazy state on the Java side after deserialization

 Description  « Hide
I'm getting the following error after flex passes an
entity back to the server.

Caused by:
org.granite.messaging.amf.io.convert.NoConverterFoundException: Cannot
convert: EA1A6A19-5627-9570-349E-8FCE2E3F82D3 to: class java.lang.Long
        at
org.granite.messaging.amf.io.convert.Converters.getConverter(Converters.java:
119)
.... (see below for full stack trace)

The error seems to occur because the columns are not being properly
aligned during the de-serialization process (from flex to java). In
this instance, the client id is being mapped back to a Long. I notice
if I add/subtract entity columns, the error seems to just shift to
another column.

I spoke with a colleague of mine and he mentioned he had the same
issue and came up with a workaround (see below).

So in my example I have three entities:
1. ReviewPlan
2. Note
3. NoteType

*ReviewPlan consists of 0 or more Notes
*Each Note may have a NoteType

Here is what is happening:
1. Flex client request a ReviewPlan. Java builds a ReviewPlan, which
has two Notes attached. Each Note has its NoteType property set to
Null (no eager fetch is done).
2. Java sends the ReviewPlan to Flex and the ReviewPlan is usable on
the Flex side.
3. On Flex end, I see the ReviewPlan with two Notes (as expected).
But I noticed that rather than each Note's NoteType being set to null
(as expected), granite attached a new NoteType with null values.
4. On the Flex end, save is clicked and the same object graph is
passed back to Java (and the error occurs).

My colleague's workaround was, in this example, to set the NoteType to
null in Flex prior to sending the graph back to Java. Doing this,
seems to correct the issue.

My thought is, if we are both experiencing this issue, it's either a
bug or we're missing something within our configuration. Why is
granite creating a new object for a property that was set to null (on
the Java side)? Any thoughts?

Below are the stack trace, JPA files, their corresponding generated AS
files, and my granite-config.xml.

I have commited a patch but I can't test it for now (I don't have any project/environment with openjpa).

Could you get the last build here: http://www.graniteds.org/bamboo/browse/GDS-CORE-633/artifact/graniteds.zip/graniteds-2.2.0.RC1.zip and tell me if it fixes your problem?

Thanks, Franck.

BTW: it is normal to get two NoteType instances on Flex side. But they should have their __initialized variables set to false and everything else set to null. The openjpa externalizer didn't test this initialized flag at deserialization time and that was (most probably) the problem.

I tested using your update, but unfortunately I'm seeing the same error.

I see where you added the check to see if the value is an instance of PersistenceCapable but after stepping through the code, I see it is never making it there.

This is because the detachedState value when processing the NoteType object is null and therefore the a new instance of DefaultExternalizer is returned.

{code}
        // Read detached state...
        String detachedState = (String)in.readObject();
        
        // New entity.
        if (detachedState == null)
         return super.newInstance(type, in);
{code}

*Also the boolean initialized value is false for the NoteType

I think making changing the order as follows resolves the issue:

// Pseudo-proxy (uninitialized entity).
if (!initialized) {
final Object id = in.readObject();
if (id != null && (!clazz.isAnnotationPresent(IdClass.class) || !clazz.getAnnotation(IdClass.class).value().equals(id.getClass()))) {
throw new RuntimeException("Id for OpenJPA pseudo-proxy should be null or IdClass (" + type + ")");
}
return null;
}

// New entity.
if (detachedState == null) {
return super.newInstance(type, in);
}

You're right, thanks for the patch. It's commited in the trunk.
Tell us if it's ok,
Franck.
