[Ur] <ctextinput source={s} /> looses input focus after every keypress

[Sergey Mironov]

Hm! The original code is sketched below. I am not interested in
catching every event from <ctextbox> but the code expresses exactly
this, so you are right, Thanks!

PS by ctextinput I meant ctextbox

fun editable (t:string) (upd:string->transaction unit) =
  <xml><active code={
     st <- source t;
     se <- source False; (*edit mode*)

     ...

     return <xml>
       <dyn signal={
         t <- signal st;
         e <- signal se;

         return
         <xml>

          <ctextbox signal={t} onkeypress={... v <- get t; rpc(upd v); ... } />

          </xml>

       }/>
     </xml>
   }/>
   </xml>
