I have been trying on a small sample on JSF. I used datatable with the binding attribute.Eventhough the submit button ie.Delete which is inside the datatable is working fine when i click on a button outside the datatable ie AddItem ..it throws an exception saying "javax.faces.el.MethodNotFoundException" . Here item is my managed bean

Attaching the sample here.Please HELP

<f:view>
<h:dataTable value="#{login.items}"
var="items" border="3" binding="#{item}" >
<h:column>
<f:facet name="header">
<f:verbatim>Id</f:verbatim>
</f:facet>
<h:commandButton value="Delete"
action="#{item.deleteItem}" />
</h:column>

<h:column>
<f:facet name="header">
<f:verbatim>Name</f:verbatim>
</f:facet>
<hutputText value="#{items.name} " />
</h:column>
</h:dataTable>

<h:commandButton action="#{item.addNewItem}" value="Additem!"/>

</h:form>
</f:view>

Following is the exception:
