Hello Bernd,
there was of cource a value binding. I stripped the example to the
bones, to see if it works eventually.
I learned meanwhile why there's the serialization. It's for the state
saving between request. But the question remains, how can state saving
ever work, when there's a class, which is not serializable
(DeferredFileOutputStream)?
Regards
Helmut
