Could not retrieve value of component with path :Error

[vish som]

Hello All,
I have a need to implement checkboxes besides the names of document names in a JSF so that they can be sent to a web service on being checked and submitted.
To visualize:
Checkbox Filename1
Checkbox Filename 2
As a first step towards achieving this target, I have identified the concerned JSP seen in the UI called ‘browse.jsp’ and added the following piece of code by adding a new column to the existing table to house the checkboxes

<%-- Primary column for checkbox in details view mode --%>
<a:column id="col10_w" primary="true" style="padding:2px;text-align:left" rendered="#{BrowseBean.browseViewMode == 'details'}">
<f:facet name="header">
<a:sortLink id="col10-sort_w" label="#{msg.name}" value="name" mode="case-insensitive" styleClass="header"/>
</f:facet>
<h:selectManyCheckbox value="#{MyBean.selectedItems}">
                    <f:selectItems value="#{MyBean.selectItems}" />
                </h:selectManyCheckbox> 
</a:column>    

Also I have written a bean MyBean which paves the way to display 3 checkboxes in that column.

    
public class MyBean implements IContextListener
{
   /** Public JSF Bean name */
   public static final String BEAN_NAME = "MyBean";
   public List<String> selectedItems;
    public List<SelectItem> selectItems;
       public void action() {
        for (String selectedItem : selectedItems) {
            System.out.println(selectedItem);
        }
    }
 
    public List<SelectItem> getSelectItems() {
        if (selectItems == null) {
            selectItems = new ArrayList<SelectItem>();
            selectItems.add(new SelectItem("value1", "label1"));
            selectItems.add(new SelectItem("value2", "label2"));
            selectItems.add(new SelectItem("value3", "label3"));
        }
        return selectItems;
    }
 
    public List<String> getSelectedItems() {
        return selectedItems;
    }
 
    public void setSelectedItems(List<String> selectedItems) {
        this.selectedItems = selectedItems;
    }
    
     public MyBean(){
...}
...}

I have added two entries into the faces-config-bean.xml
1) Added the setters to the BrowseBean.jsp which is the parent governing bean responsible for the default display of filenames

 
<managed-bean>
      <description>
         The bean that holds folder browse state.
      </description>
      <managed-bean-name>BrowseBean</managed-bean-name>
      <managed-bean-class>org.alfresco.web.bean.BrowseBean</managed-bean-class>
      <managed-bean-scope>session</managed-bean-scope>
      <managed-property>
         <property-name>navigator</property-name>
         <value>#{NavigationBean}</value>
      </managed-property>
      ...
	   <managed-property>
         <property-name>selectItems</property-name>
         <value>#{MyBean}</value>
      </managed-property>
	     <managed-property>
         <property-name>selectedItems</property-name>
         <value>#{MyBean}</value>
      </managed-property>
   </managed-bean>

2) Added the Bean declaration for the newly created Mybean like BrowseBean (just below it).

  
<managed-bean>
      <description>
         The bean that holds folder browse state.
      </description>
      <managed-bean-name>MyBean</managed-bean-name>
      <managed-bean-class>org.alfresco.web.bean.MyBean</managed-bean-class>
      <managed-bean-scope>session</managed-bean-scope>
      <managed-property>
         <property-name>navigator</property-name>
         <value>#{NavigationBean}</value>
      </managed-property>
      <managed-property>
         <property-name>nodeService</property-name>
         <value>#{NodeService}</value>
      </managed-property>
      <managed-property>
         <property-name>searchService</property-name>
         <value>#{SearchService}</value>
      </managed-property>
      <managed-property>
         <property-name>lockService</property-name>
         <value>#{LockService}</value>
      </managed-property>
      <managed-property>
         <property-name>dictionaryService</property-name>
         <value>#{DictionaryService}</value>
      </managed-property>
      <managed-property>
         <property-name>fileFolderService</property-name>
         <value>#{FileFolderService}</value>
      </managed-property>
      <managed-property>
         <property-name>userPreferencesBean</property-name>
         <value>#{UserPreferencesBean}</value>
      </managed-property>
      <managed-property>
         <property-name>multilingualContentService</property-name>
         <value>#{MultilingualContentService}</value>
      </managed-property>
	     <managed-property>
         <property-name>selectItems</property-name>
         <value>#{MyBean}</value>
      </managed-property>
	     <managed-property>
         <property-name>selectedItems</property-name>
         <value>#{MyBean}</value>
      </managed-property>
   </managed-bean>

After making these changes , I am getting the following error

javax.faces.FacesException: javax.faces.FacesException: Could not retrieve value of component with path : {Component-Path : [Class: javax.faces.component.UIViewRoot,ViewId: /jsp/login.jsp][Class: javax.faces.component.html.HtmlForm,Id: loginForm][Class: javax.faces.component.html.HtmlInputText,Id: user-name]}

Can anyone kindly help me in fixing this.
Thank You
