Problem integrating JSF with Spring

Question

Here is faces-config.xml
<application>
<el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver>
</application>
<managed-bean>
<managed-bean-name>dateuser</managed-bean-name>
<managed-bean-class>com.datesite.user.DateUser</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
<managed-property>
<property-name>entityManagerDateUser</property-name>
<property-class>com.datesite.user.EntityManagerDateUser</property-class>
<value>#{entityManagerDateUser}</value>
</managed-property>
</managed-bean>
</faces-config>
Here is the deployment exception
javax.faces.FacesException: javax.faces.FacesException: Error performing conversion of value com.datesite.user.EntityM
anagerDateUser@380b4f9 of type class $Proxy35 to type class com.datesite.user.EntityManagerDateUser for managed bean d
ateuser.
at com.sun.faces.application.ApplicationAssociate.createAndMaybeStoreManagedBeans(ApplicationAssociate.java:53

Seems liek it can't figure out which class to instantiate?
Please help.

I've used the spring integration but I have not encountered this issue.
It looks to me like Spring is giving out a proxy implementation that cannot be used in place of the actual class. Some things you might want to try:
1) Configure Spring to create the bean upon initialization instead of waiting for it to be used.
2) Remove any aspect-oriented configuration from the spring bean (including transaction support) to see if that makes a difference.
3) Consider the possibility of a class loading conflict, i.e. was the spring container loaded by a different class loader than the one for the web application?
Finally I would consider posting this on the forums at springframework.org.
