Hello Senthilchettyin,

I performed a number of modifications to your code so it can work as expected:

The zul file:

<window title="Example for ZK MVVM List Box" width="500px"
   apply="org.zkoss.bind.BindComposer"
 viewModel="@id('vm') @init('pkg$.ListBox2')">
 <label value="You are using: ${desktop.webApp.version}" />
    <separator></separator>
 <listbox id="personsLstbx" model="@load(vm.allPersons)" checkmark="true" mold="paging" pageSize="3"
       multiple="true"
     selectedItems="@bind(vm.selectedPersons)">
       <listhead sizable="true">
         <listheader label="First Name" sortDirection="ascending"
             sort="auto(firstName)" />
            <listheader label="Last Name" sort="auto(lastName)" />
            <listheader label="Email" sort="auto(email)" />
       </listhead>
       <template name="model" var="p1">
          <listitem>
                <listcell label="@load(p1.firstName)" />
              <listcell label="@load(p1.lastName)" />
               <listcell label="@load(p1.email)" />
          </listitem>
       </template>
   </listbox>
    <button label="Select All"
     onClick="@command('onSelectAll')">
 </button>
</window>

And the java class:

package pkg$;

import java.util.ArrayList;
import java.util.List;

import org.zkoss.bind.annotation.AfterCompose;
import org.zkoss.bind.annotation.Command;
import org.zkoss.bind.annotation.ContextParam;
import org.zkoss.bind.annotation.ContextType;
import org.zkoss.bind.annotation.NotifyChange;
import org.zkoss.zk.ui.Component;
import org.zkoss.zk.ui.select.Selectors;
import org.zkoss.zk.ui.select.annotation.Wire;
import org.zkoss.zul.Listbox;

public class ListBox2  {

  @Wire
  private Listbox personsLstbx;

  private List<person> allPersons = new ArrayList<person>();
  private person selectedPerson;
  private List<person> selectedPersons;

  @AfterCompose
  public void afterCompose(@ContextParam(ContextType.VIEW) Component view) {

      Selectors.wireComponents(view, this, false);

  }

    public person getSelectedPerson() {
     return selectedPerson;
  }



   public void setSelectedPerson(person selectedPerson) {
      this.selectedPerson = selectedPerson;
   }

   public List<person> getSelectedPersons() {
        return selectedPersons;
 }

   public void setSelectedPersons(List<person> selectedPersons) {
        this.selectedPersons = selectedPersons;
 }

   public List<person> getAllPersons() {
     return allPersons;
  }

   public void setAllPersons(List<person> allPersons) {
      this.allPersons = allPersons;
   }

   public ListBox2() {

     allPersons.add(new person("John 1", "James", "JohnJames@yahoo.com"));
     allPersons.add(new person("Taylor 2", "Harris", "Harris@yahoo.com"));
     allPersons.add(new person("Allen 3", "Scott", "Scott@yahoo.com"));
       allPersons.add(new person("John 4", "James", "JohnJames@yahoo.com"));
     allPersons.add(new person("Taylor 5", "Harris", "Harris@yahoo.com"));
     allPersons.add(new person("Allen 6", "Scott", "Scott@yahoo.com"));
       allPersons.add(new person("John 7", "James", "JohnJames@yahoo.com"));
     allPersons.add(new person("Taylor 8", "Harris", "Harris@yahoo.com"));
     allPersons.add(new person("Allen 9", "Scott", "Scott@yahoo.com"));


    }

   @Command
   @NotifyChange({"selectedPersons"})
      public void onSelectAll()
    {
      this.selectedPersons = new ArrayList<person>();

        for (person p: allPersons) {
            selectedPersons.add(p);
        }

    }

   // inner class
  public class person {
       private String firstName;
       private String lastName;
        private String email;

       public person(String firstName, String lastName, String email) {
            this.firstName = firstName;
         this.lastName = lastName;
           this.email = email;
     }

       public String getFirstName() {
          return firstName;
       }

       public void setFirstName(String firstName) {
            this.firstName = firstName;
     }

       public String getLastName() {
           return lastName;
        }

       public void setLastName(String lastName) {
          this.lastName = lastName;
       }

       public String getEmail() {
          return email;
       }

       public void setEmail(String email) {
            this.email = email;
     }

   }
}

The problem was that there was a conflict when you set both selectedItem, and selectedItems (You only need selectedItems).

Best Regards,

Darksu
