JSF client side state saving

Question

I know the following thing
**When the HTML form is submitted it carries the view state value back to the server in the form of an HTTP parameter. JSF uses the value of this parameter to reconstruct the view during the restore view phase. The view is restored by reversing the process used to obtain the view state: it is decoded and deserialized.**
so I have tried to run the following code in jsp page with jsf tags I was able to see the input hidden parameter with facesview state and its value
<f:view>
        <h1>Hello World!</h1>
        <h:form>
           <h:inputText value="#{phonebean.phonenumber}" converter="Pconverter" id="input" >
        </h:inputText>
       <h:outputText value="rakeshggh" />
       <h:commandButton action="test" value="submit" />
       </h:form>
        </f:view>the encoded html output i was able to view the following hidden value which holds the view state as foolows
<input type="hidden" name="javax.faces.ViewState" id="javax.faces.ViewState" value="H4s......very big value />
but my question is when i have removed the jsf form tag but had some components in the view but there was no hidden element which holds the view state on
client side , so I was wondering how the view state that stores on the client side goes to the server and gets reconstructed i.e the tree of components .It would
be great if someone throws light on this I would appreciate it !!!
