String renderStamp = form.getAttributes().get(RENDER_STAMP_ATTR).toString();

RENDER_STAMP_ATTR is removed during form submit. If you try to make double submit attribute is missing in the map and NPE raised.



    Steps to Reproduce: 
1. Create test.xhml view which contains following form definition:

<h:form>
            <s:token/>
            <h:inputText id="name" value="#{test.name}" /> 
            <h:commandButton value="Submit" action="/page/test1.seam" />
</h:form>

2. Create test1.xhtml view (used to navigate from test.xhtml)

3. Open test.xhtml view in browser (IE, Firefox etc.)

4. Press form submit button,  test1.xhtml should be opened in browser 

5. Press browser's BACK button, test.view should be displayed in browser

6. Press submit button once again (this is a double submit)

7. NPE is raised  (seam debug page is opened)

Test views are attached to the defect.
