[Trinidad] set focus after partial submit

[Rottstock, Sven]

Hi,

i have the following JavaScript code that should execute a partial
submit. After the response is completed the focus should be set on the
input element that have triggered the request.

<tr:inputText label="#{bundle.searchPattern}"
  value="#{myBean.searchPattern}"
  onkeyup="clickButton_afterEnter(event, submitBtn, this);" />

<tr:commandButton id="submitSearch" action="#{myBean.executeSearch}"
  text="#{bundle.search}" partialSubmit="true" />

<tr:table partialTriggers="submitSearch" value="#{myBean.tableData}">
  <!-- my columns goes here -->
</tr:table>

<script type="text/javascript" language="javascript">
  // <![CDATA[
    var submitBtn = window.document.getElementById("submitSearch");
    var lastFocusElem = null;
                                
    function setFocus(state)
    {
      if(state != TrRequestQueue.STATE_BUSY)
      {
        if(lastFocusElem != null)
        {
          lastFocusElem.focus();
          lastFocusElem = null;
        }
 
TrPage.getInstance().getRequestQueue().removeStateChangeListener(setFocu
s);
      }
    }
                                
    function clickButton_afterEnter(evt, button, source)
    {
      evt = (evt) ? evt : (window.event) ? window.event : "";
      var keycode = evt.which ? evt.which : (evt.keyCode) ? evt.keyCode
: window.event.keyCode;
      if(keycode == 13)
      {
        var btn = (button == null) ? submitBtn : button;
        var form = document.forms[0];
        if(btn != null && form != null)
        {
          lastFocusElem = source;
 
TrPage.getInstance().getRequestQueue().addStateChangeListener(setFocus);
          TrPage._autoSubmit(form.id, btn.id, evt, true, 0);
        }
      }
    }
  // ]]>
</script>

Unfortunately the focus is lost from the input field if I have pressed
the enter key and the response was completed.
Does anybody have an idea what is going wrong here?

Regards,

Sven
