Are you using IExternalizable on any of your objects by any chance?

This is due to an unexpected error during serialization. If you could send me a reproducible test case I would very much like to know what caused this... the best way would be to zip up the code and rename the zip file with a .pete extension (as .zip files will be denied by our email system).

Thanks,

Pete

Subject: [flexcoders] Flex Data Services - Client.Data.UnderFlow

Hi there,

Im currently trying to use Flex Data Services and Hibernate to link my web application with a MySQL database.

All Java classes are written and mapped to the database with hibernate.

AS3 classes are written and mapped to Java classes with [Managed] and [RemoteClass()].

The data-management-config file is filled with one destination per class and the default-channel is polling-amf.

The first class is the Client one and contains all personal data.

The second one is the User class. It contains special data and a reference to a Client.

The last class is the Contract one. This one contains contract data, a reference to a Client and a collection of Users to indicate which users are concerned by the current contract.

The web application contains 2 states:

- the default one to display clients contracts in a custom component using a DataService to retrieve data (destination = hibernate.Contract)

- the second one to display clients and users data in a custom component containing two DataServices to retrieve data (destinations = hibernate.Client and hibernate.User

So when a client visits the website, the default state is displayed without any problem. An error is displayed when the client changes the current state of the application but new data are well displayed. Here is the error:

Error #2044: NetStatusEvent non pris en charge : level=error, code=Client.Data.UnderFlow

I tried to disconnect the DataService, release the collection but I have no idea on how to solve this problem. Does somebody already encounter this problem or know how to solve it?

Thanks.
