when i'm doing the same example with a sample result of List without a converter, it works corretctly.
but my converter seems correct to me.. or am i wrong?

by using my original code (with the converter and my model objects) i can now switch the items to rights.
now there is a validation error:
userForm:orgUnitPickList: Validierungs-Fehler: Wert nicht gueltig. (validation error: invalid value)

where could that come from?

btw: why isn't there an edit button!?

Hi,

Could you please check if list items implement equals()/hashCode() in the right way?

Hi,

try
private List pickListResult;
instead of
private ArrayList pickListResult;
in your bean

Could you please check if list items implement equals()/hashCode() in the right way?

if read about this concerning listshuttles.
would you mind telling me the "right way"? (i don't nevessarily want complete code or something like this. i'd just like to know what they have to do in contrast to the "normal way")
sorry for this possible stupid question :(

thanks in advance,
Tim
