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. -Andrew On Fri, Sep 4, 2009 at 7:32 AM, Roeder, Andreas<[email protected]> wrote: > I'm trying to create generic selectOneChoice elements.
