--------------------------------------

I thought as much.

Thanks for the focus tip, i already tried it before. 

    <h:form id="myform">
        <h:panelGrid columns="2">
            <h:inputText id="myinput" value="#{userBean.name}">
                <a4j:support event="onkeyup" reRender="myform" focus="myinput"/>
            </h:inputText>
            <h:outputText id="outtext" value="#{userBean.name}" />
        </h:panelGrid>
    </h:form>

But when you use it that way the whole text in the inputText will be selected after rerendering. The position cursor has changed.

F.e.
Before: selection start = x, selection end = x
After: selection start = 0, selection end =n-1

(x is the position within the text, n is the length of the text)

> A control within a parent form looses its focus when the parent form is rerendered. The rerendering was forced by an event fired from the child control. See the source (based on http://livedemo.exadel.com/richfaces-demo/richfaces/support.jsf?c=support)
>     <h:form id="myform">
>         <h:panelGrid columns="2">
>             <h:inputText id="myinput" value="#{userBean.name}">
>                 <a4j:support event="onkeyup" reRender="myform" />
>             </h:inputText>
>             <h:outputText id="outtext" value="#{userBean.name}" />
>         </h:panelGrid>
>     </h:form>
> Notice the difference. Instead of  "outtext" "myform" will be rerendered.
> Background: You have a detail form with several components. Every control on the form changes the internal state. The view represents the actual state, so the whole form has to be rerendered. But when you rerender the parent form, the focus/selection state of the actual component is lost.
