so the workflow looks like:
some action ( submit? ) on page 1
-> generate and set data on page 2
-> display page 2 (data is ok)
-> submit form (page 2)
-> page 2 displayed, data is lost
Briefly looking at the code it seems you just have to add a hidden with
the value binding ognl:someData inside your form.

Hi!
I'm trying to edit a set of values, and it works fine if I use
@Persist on the data I'm trying to edit.
I would like to avoid @Persist as much as I can as it bloats the session.
Therefore I would like some guidance on how to do it without @Persist
I would like to point out that I have tried @Persist("client"), it
didn't work, the values where reverted the second submit, try it
yourselves.
Another thing I considered was using the @Hidden component, but it
behaved like the @Persist("client") (reverted the values on the second
submit)
Please help!
This is what I've got:

SomeData data = getSomeData();
data.setValues(new TreeSet<ValuePair>());
for(int i = 0; i < getSize(); i++) {
data.getValues().add(new ValuePair(i + ": ", "" +
(int)(Math.random()*100)));
}
AnotherPage p = getAnotherPage();
p.setSomeData(data);
return p;
}
}
