Mario Ivankovits commented on ORCHESTRA-3:
------------------------------------------

During debugging the situation I found a workaround you can try.
Add the aop:scoped-proxy to the "persistentContextConversationInterceptor" 
bean. It should look like the following then:

        <bean id="persistentContextConversationInterceptor"
                  
class="org.apache.myfaces.orchestra.conversation.spring.PersistenceContextConversationInterceptor">
                <aop:scoped-proxy/>
                <property name="persistenceContextFactory" 
ref="persistentContextFactory"/>
        </bean>

Due to the aop:scoped-proxy configuration the initialization of the dataSource 
will happen on the first real request to the scope and thus happens after the 
spring property configuration replacement.
