ADF: Default cursor/focus to input field using javascript

Sometimes when default properties won't work, we can use JS to set initial focus.

• jquery is required & can be downloaded from (http://jquery.com/).
• A dummy <af:clientAttribute> is added for field on which initial focus is required.
• A <af:clientListener> method is added on "load" type.

<f:view>
    <af:document id="d1">
      <f:facet name="metaContainer">
        <af:resource type="javascript" source="/jquery-1.7.min.js"/>
        <af:resource type="javascript">
          function onLoadFocus() {
              $('input[type="text"]').each(function () {
                  if (isDefaultFocusField(this.name) == 'Y') {
                      this.focus();
                  }
              });
          }

          function isDefaultFocusField(compId) {
              try {
                  var adfComp = AdfPage.PAGE.findComponentByAbsoluteId(compId);
                  return adfComp.getProperty("defaultFocusField");
              }
              catch (err) {
              }
          }
        </af:resource>
