Thanx a lot, that worked like a glue. Just one problem is left: all the
selectOneChoice components are on required="true". How can I avoid the
validation?
I already tried to call at the end of the ValueChangeListener the call:
FacesContext.getCurrentInstance().renderResponse();
but no success.

Betreff: Re: [Trinidad] How to use an iterator, selectOneChoice and
partialTriggers?
If you give partial triggers an EL expression it must evaluate to type
String[]. The value change listener is fired for the current iteration, so if
you click item 3, the event will be broadcast for the selectOneChoice inside
the index 2 of tr:iterator. To move the iterator to a new index you need to
save the current row index, set the new index, evaluate code and then set it
back.
An iterator stamps out one component and a component only has 1 ID, so you
cannot put EL in the ID like you did below. I would advise using <f:attribute/>
if you need to store the ID on the component, but just give the choice a static
ID.
The resulting IDs on the client will be like "i1:0:soc1", "i1:1:soc1", etc if
your iterator had ID "i1" and your selectOneChoice had ID "soc1". So the :#: in
between represents the stamp index.
