listShuttle problem

[Predrag Ristic]

I'm trying to use rich:listShuttle component in my seam application.Source value and target value attributes are set like this:
sourceValue="#{myBeanClass.availableTrainingParticipants}",targetValue="#{myBeanClass.chosenTrainingParticipants}" (myBeanClass is manage bean class and availableTrainingParticipants and chosenTrainingParticipants are List<String>).I'me getting this error:

sourceValue="#{myBeanClass.availableTrainingParticipants}": Property 'availableTrainingParticipants' not found on type org.javassist.tmp.java.lang.Object_$$_javassist_seam_2

Can someone tell my why?

I think one of them has to be Set.

The ListShuttle control and its friends have a very irritating and under-documented core requirement.

The actual state of the control is not maintained on the backing bean, but in your browser, so the control has to be able to serialize the entire object being shuttled around as a character string (toString) which is then used as the sole argument to a a constructor (public MyObject(String serializedMyObject) ) used to re-create it in the server.
