In my pageBlockTable, when the "Quantity" is changed, it would be a action and reRender this table,

when the table is rerenderd, the focus in this table would be lost, so i'm trying to re-focus the last element.

here is my code:

<apex:page controller="Mycontroller">
<script type="text/javascript">
   var elementFocus = null;
   function setFocus(){
       elementFocus = document.activeElement;
   function retainFocus(){
 <apex:form >
      <apex:pageBlockTable value="{!wrappers}" var="wrapper" id="wtable">
         <apex:column headerValue="Quantity">
             <apex:inputField value="{!wrapper.sub.Quantity__c}" id="Quantity__c">
                 <apex:actionSupport event="onchange" action="{!doSomething}"

                     <!-- before take action, set current focus. oncomplete, retain that focus -->
                     onbeforedomupdate="return setFocus()" rerender="wtable" oncomplete="return retainFocus()">
         <apex:column headerValue="SalesPrice">
            <apex:inputField value="{!wrapper.sub.SalesPrice__c}" id="SalesPrice__c"/>

 i use javascript to retain focus, and the alert also shows the right id, but elementFocus.focus(); just don't work.

should i include some other script?

<script type="text/javascript">
   var elementFocus = null;
   function setFocus(){
       elementFocus = document.activeElement;
   function retainFocus(){
       alert(elementFocus.id); //when debug, it shows the same value as the id in setFocus()
elementFocus.focus(); } </script>

 Any help would be much appreciated!

I want to concatenate two object IDs in order to make a hash value for a map, but this doesn't work:


conversionMap.put(entry.Pricebook2Id + entry.Product2Id), entry);

If I could convert the IDs to strings first, then I should be able to concatenate them in this way.  But, while there is a function to convert a string to an ID, I can't find any way to convert an ID to a string.  Anybody know how to do that?  Or, a better way to do what I'm trying to do?
