Dear all,

Is there any guide I need to follow in order to be able to persist an object from a previous screen that is involved in a pageflow?

Since I get this stacktrace:

When I wanted to persist a Used object that is submitted from previous screen (1st screen).

When I looked into debug.seam while on the 2nd page, the object is there/instantiated but when I hit submit on that 2nd page I get this stacktrace.

Can anybody give a clue about this? I've tried looking the examples but I couldn't find the ones that uses two object from two different screen persisted on one transaction

Regards,
joshua
