Hi guys,

We have created a List implementation that allows paged data that can be used with rich:datascroller.  It works very well in general, only performing a query each time a new page of data is requested.

However, I have this intermittent problem when ManagedEntityIdentityInterceptor tries to replace this with an ArrayList  (or so I'm guessing).

This is what I see...

java.lang.IllegalArgumentException: Could not set field value by reflection: BatchAdminBean.txnResultList on: BatchAdminBean with value: class java.util.ArrayList
     at org.jboss.seam.util.Reflections.set(Reflections.java:79)
     at org.jboss.seam.persistence.ManagedEntityIdentityInterceptor.getFromWrapper(ManagedEntityIdentityInterceptor.java:196)
     at org.jboss.seam.persistence.ManagedEntityIdentityInterceptor.entityIdsToRefs(ManagedEntityIdentityInterceptor.java:129)
     at org.jboss.seam.persistence.ManagedEntityIdentityInterceptor.aroundInvoke(ManagedEntityIdentityInterceptor.java:46)

....

Caused by: java.lang.IllegalArgumentException
     at sun.reflect.UnsafeObjectFieldAccessorImpl.set(UnsafeObjectFieldAccessorImpl.java:63)
     at java.lang.reflect.Field.set(Field.java:656)
     at org.jboss.seam.util.Reflections.set(Reflections.java:64)

Any ideas?

Currently the LazyList implementation extends AbstractList and implements List and Serializable.  I tried changing it to extend ArrayList, but still have the same problem.

thanks in advance,
Daniel.
