hello

when I did:

                    <a4j:jsFunction name="fjslat_long" reRender="latid,longid"  action="#{userBean.actionlat_long}" >

                    <a4j:actionparam name="param1" assignTo="#{userBean.jslat}" />

                    <a4j:actionparam name="param2" assignTo="#{userBean.jslong}" />     

                    </a4j:jsFunction>

it did twice same action in userBean.actionlat_long.

that is to say:

  public void actionlat_long() { 

              System.out.print("actionlat_long  jslat2 ----- "+getJslat());

              System.out.println("actionlat_long  jslong2 "+ getJslong());

     ...

it makes double print.

in order to overcome this

I added and omitted "action="#{userBean.actionlat_long}" in a4j:jsFunction

<a4j:support event="oncomplete" action="#{userBean.actionlat_long}" />      

but it was problematic

what can I do

regards
