I have this code, taken from Jeff Douglas' dynamic search page (thanks very much).

      <script type="text/javascript">
      function doSearch() {
        searchServer(
 document.getElementById("contributorFname").value,
          document.getElementById("contributorLname").value,
          document.getElementById("MOC_Lname").value,
          document.getElementById("soqlLimitPage").options[document.getElementById("soqlLimitPage").selectedIndex].value  // LAST note comma
          );         
      }
      </script> 
 
      <apex:actionFunction name="searchServer" action="{!runSearch}" rerender="results,debug,errors">
          <apex:param name="contributorFname" value="" />
          <apex:param name="contributorLname" value="" />
          <apex:param name="MOC_Lname" value="" />
          <apex:param name="soqlLimitPage" value="" />
      </apex:actionFunction>
 

 If I enter the code from a field using onKeyUp it works fine. The query runs in the controller and the page rerenders and all is good. Life is great.

 If I enter the code from a button using onClick, the query runs in the controller, I can see it in the debug logs. But.. the page does not rerender.

Is there a difference between onClick and onKeyUp? How else can I force the rerender of the results? (I can provide more code if neccessary.)

I am a coder from way back when but a newbie to java, JS, Apex, and VisualForce.

Thanks for any help... Bob
