Destroying a conversation using conversation picker....
cRUDUserController is a conversation scoped controller.
@SuppressWarnings("serial")
@Stateful // A component stays in existance for the duration of the Scope (conversation in this instance).
@Name("cRUDUserController") // Name used within SEAM for an instance of this class.
@Conversational // Scope that this class exists in.
It holds the Mode it is currently being required to "run" in and outjects this mode to the View (and this is used in pages.xml for the conversation name).
/** * Bijected the mode that this Controller is currently being driven in. * This is used by the GUI to know how to configure the screen. */ @Out private Mode mode;
Where Mode maps to an Enum:
/**
* The mode that this Controller is currently being driven in.
*/
public enum Mode {CREATE, READ, UPDATE, DELETE};
I can swap conversations ok with the conversation picker; but I cannot destroy the conversation for the following reason:

Why would Seam be trying to re-read the cRUDUserController for that conversation after it has been destoyed?
