Hibernate serialisation failing
I have multiple sessionFactories, and I am using the spring-flex-core-1.5.0.M2.jar release, but when I try to return an object to the Flex client, I get the following error:
Code:

It seems to be failing when trying to access the Hibernate proxy. I think Spring/Flex should be setting this value to a null here, but for some reason it isn't.
Here is my Spring config, I have tried it with and without the ConversionService being defined:
Code:
<flex:message-broker>
<flex:config-processor ref="hibernateConfigProcessor" />
</flex:message-broker>
<bean id="hibernateConfigProcessor" class="org.springframework.flex.core.io.HibernateConfigProcessor">
<property name="sessionFactory" ref="sessionFactoryProsoc"/>
<!--<property name="conversionService" ref="conversionService" />-->
</bean>
<bean id="conversionService" class="org.springframework.core.convert.support.GenericConversionService"/>
Hints appreciated.
