some of components within jsf/primefaces implement namingcontainer inerface. such components affect way client ids of children generated. examples of such components include <h:form> (htmlform class) , <p:accordionpanel> (accordionpanel class). while seem aware of former, did not know latter naming container well.
when want ajax-update given component need specify either id, in case it's located relative same naming container, or client id, in case it's relative view root. tying view structure update=":formid:accordionpanelid:datatableid".
the last issue concern every component must have id set found within component tree , surely unique. in case supply id of own, in id="mycomponentid", you set id component. otherwise component id autogenerated jsf framework you: that's why ind j_idt43 ids.
to sum up, need explicitly specify id accordion panel , include in path to-be-updated component (exactly proposed in wittakarn's answer).
