        for (String s : attNames) {
            Object viewRowAttributeValue = pViewRow.getAttribute(s);
            vcRow.setAttribute(s, viewRowAttributeValue);
        }
        vc.add(vcRow);
        pViewObject.getViewCriteriaManager().putViewCriteria(pSearchName, vc);
        JUSearchBindingCustomizer.createPersonalization(pViewObject, vc);
    }


How to retrieve user specific defaults from MDS ?
Answer : 


  /**
     * Retrieves all the saved search names from MDS for a given
     * Viewobject based on logged in user ID
     * @param pViewObject
     * @return
     */

        ViewCriteriaRow vcRow = (ViewCriteriaRow)vc.get(0);
        String[] attNames = vcRow.getAttributeNames();
        StringBuffer buf = null;
        for (String s : attNames) {
            Object vcRowAttributeValue = vcRow.getAttribute(s);
            if (vcRowAttributeValue != null) {

Implementation :  Have below code in managed/backing bean.


         FacesContext fctx = FacesContext.getCurrentInstance();
         ExtendedRenderKitService erks = Service.getRenderKitService(fctx, ExtendedRenderKitService.class);      
         // Invoke a java script method name called showConfPopup()' with two parameters, You can pass any value 
         erks.addScript(fctx, "showConfPopup('" + popupClientId + "', '" + tabClientId + "')");  

Java Script Method , 

Include below code in any jspx in <af:document> element


<af:document>
<f:facet name="metaContainer">
          <af:resource type="javascript">

                  function showConfPopup(popupId, tabId){
                       alert("Hello");
                  }

Another way of invoking

<af:document id="d1">

 

  <af:clientListener method="onPageLoad" type="load"/>

  <f:facet name="metaContainer">

    <af:resource type="javascript">

      function onPageLoad(evt) {

If you have encountered an error message using '&&' operator in <af:resource> , then try replacing '&&' with '&amp:&amp;'

 if (butPressed == 'YES' &&  (editGenInfo == 'Y'))


 if (butPressed == 'YES' &amp;&amp;  (editGenInfo == 'Y'))
