-------------------------------------------------------------------

This is a spec bug in JSF 1.2:
http://java.sun.com/javaee/javaserverfaces/1.2/docs/api/javax/faces/render/ResponseStateManager.html#VIEW_STATE_PARAM

However, the id is actually not needed (in MyFaces) unless some special (AJAX) components wanna do some Javascript magic.

Therefore I added a (MyFaces specific) config parameter:
  org.apache.myfaces.RENDER_VIEWSTATE_ID
The default value is true for backwards compatibility.

So, adding
    <context-param>
        <description>
            Do not render the "javax.jsf.ViewState" id attribute for
            view state hidden inputs. Necessary for valid XHTML on multiple forms on one page.
        </description>
        <param-name>org.apache.myfaces.RENDER_VIEWSTATE_ID</param-name>
        <param-value>false</param-value>
    </context-param>
to your web.xml makes multiple form jsf pages XHTML valid.

> On pages with more than one <h:form>, each one generates an element which has always the same id, which is invalid HTML. 
> Looks like this:
> ...</script><input type="hidden" name="javax.faces.ViewState" id="javax.faces.ViewState" value="..." /></form>
> I tried to put it inside <f:subview> as a workaround, but that did not work either (the ids did not change).
