Invalid AM3 serialization of eager-loaded enum Set/List (CollectionOfElements)

Created: 03/Feb/08 02:36 PM   Updated: 27/May/08 04:54 PM   Resolved: 27/May/08 04:54 PM
Component/s: AMF3 (de)serialization
Affects Version/s: 1.0.0_RC2
Fix Version/s: None


 Description  « Hide
My entity bean has a field like:

@CollectionOfElements(fetch = FetchType.EAGER)
@Enumerated(EnumType.STRING)
@JoinTable(name = "user_event_types", joinColumns = @JoinColumn(name = "user_id"))
private Set<EventMessageEventType> eventTypes;


where EventMessageEventType is an enum:

public enum EventMessageEventType {
ChannelMessage, BlogEntry, CleanupEvictorQueue
}

I get an error by deserializing the am3-message:

"ArgumentError: Error #2004: Einer der Parameter ist ungültig.
at flash.utils::ObjectInput/readObject()
at com.maxtrading.user.entities::UserBase/readExternal()[E:\Projekte\pvs\bardtke\web\st\generated\main\mxml\com\maxtrading\user\entities\UserBase.as:155]
"

        override public function readExternal(input:IDataInput):void {
            super.readExternal(input);
            if (meta::isInitialized()) {
                _activationKey = input.readObject() as String;
                _email = input.readObject() as String;
                _enabled = input.readObject() as Boolean;
line 155 ->> _eventTypes = input.readObject() as ArrayCollection;
                _invoiceAccount = input.readObject() as Account;



The loaded entity-field is an empty set.

I debuuged it down to swriteAMF3Array:

    protected void writeAMF3Array(Object array) throws IOException {
        if (debugMore) logMore.debug("writeAMF3Array(array=%s)", array);

        write(AMF3_ARRAY);

        int index = indexOfStoredObjects(array);
        if (index >= 0)
            writeAMF3IntegerData(index << 1);
        else {
            addToStoredObjects(array);

            int length = Array.getLength(array);
            writeAMF3IntegerData(length << 1 | 0x01);
            write(0x01);
            for (int i = 0; i < length; i++)
                writeObject(Array.get(array, i));
        }
    }


In that case, index = -1 and the length property is set to 0. The expression "writeAMF3IntegerData(length << 1 | 0x01);" will write "1" into the stream, but then, no object is written, cause length is 0. May this be the bug?

I tried with a filled set of enums, but I get the same problem with the deserialization. Is looks as if this is a problem with enums.

Frankk,

are you still working on this issue? I still cannot use granite, because of the faulty de/serialization. Please have a look at it.
If you need help to locate or setup the problem, just give me a note.

Cheers
Carsten

Hi Franck.

I still cannot use your nice work, because of the wrong de-/serialization of such an entity-field:

@CollectionOfElements(fetch = FetchType.EAGER)
@Enumerated(EnumType.STRING)
@JoinTable(name = "user_event_types", joinColumns = @JoinColumn(name = "user_id"))
private Set<EventMessageEventTypeEnum> eventTypes = new HashSet<EventMessageEventTypeEnum>();


The serializer looks not that bad, but I do not have a deep knowledge of the requested am3-stream.

The corresponding debug output for an empty set is:

The GAS-generator created this readExternal(..) function for the entity:

        override public function readExternal(input:IDataInput):void {
            super.readExternal(input);
            if (meta::isInitialized()) {
                _activationKey = input.readObject() as String;
                _email = input.readObject() as String;
                _enabled = input.readObject() as Boolean;


line155-> _eventTypes = input.readObject() as ListCollectionView;


                _invoiceAccount = input.readObject() as Account;
                _invoices = input.readObject() as ListCollectionView;
                _loginKey = input.readObject() as String;
                _password = input.readObject() as String;
                _reasonNotEnabled = input.readObject() as String;
                _referrer = input.readObject() as User;
                _referreredUsers = input.readObject() as ListCollectionView;
                _sessionUUID = input.readObject() as String;
                _subscriptions = input.readObject() as ListCollectionView;
                _systemUser = input.readObject() as Boolean;
                _userDetails = input.readObject() as UserDetail;
                _userManagementDetails = input.readObject() as ListCollectionView;
                _userRoles = input.readObject() as ListCollectionView;
                _username = input.readObject() as String;
            }
        }


Everything works fine, until I reach

                _eventTypes = input.readObject() as ListCollectionView;

Here an exception is thrown:

ArgumentError: Error #2004: One of the parameter ist invalid.
at ObjectInput/readObject()
at com.maxtrading.user.entities::UserBase/readExternal()[E:\Projekte\workspace\portal\web\st\generated\main\mxml\com\maxtrading\user\entities\UserBase.as:155]



Can you please have a look at the problem or give me a hint what I can try at my side - I really would like to use your software package in my project.

Thanks

Frankk,

finally I got it to work. There were several issues to resolve the problem:

- the granite-config.xml format has been changed, I tried took the latest one.
- the compiler-options where wrong (e.g. in eclipse - I had to add the
      -include-libraries lib/granite.swc
      -include-libraries lib/granite-hibernate.swc
to the compiler path.

You can close this bug!
