ExtendedDataTable first selectionChange event has no ViewSateParam

[cheeray]

View has two forms:

<h:form id="tableForm" >

     <rich:extendedDataTable id="transactions_table" var="transaction"

       value="#{backBean.transactions}" rowKeyVar="row"

       selection="#{backBean.selection}"

       selectionMode="multipleKeyboardFree">

       <a4j:ajax event="selectionchange"

       listener="#{backBean.selectionListener}"

       render="transactions_selection"/>

...

     </rich:extendedDataTable>

<a4j:outputPanel id="transactions_selection">

<h:outputText value="Selected Transactions:" />

     <ui:repeat var="selectedTransaction"

     value="#{backBean.selectedTransactions}">

          <h:outputText value="#{selectedTransaction}" />

    </ui:repeat>

</a4j:outputPanel>

</form>

<h:form id="calculationForm" >

     <rich:extendedDataTable id="calculation_table" var="transaction"

       value="#{backBean.transactions}" rowKeyVar="row"

       selection="#{backBean.candidates}"

       selectionMode="multipleKeyboardFree">

       <a4j:ajax event="selectionchange"

       listener="#{backBean.calculate}"

       render="transactions_calculation"/>

...

     </rich:extendedDataTable>

<a4j:outputPanel id="transactions_calculation">

     <ui:repeat var="calculated"

     value="#{backBean.calculatedTransactions}">

          <h:outputText value="#{calculated.value}" />

    </ui:repeat>

</a4j:outputPanel>

</form>

There's no ViewStateParam in the form data, thus the JSF container skipped phases between restore view and render view.

Inspected the source code, an hidden input:

<input type="hidden" name="javax.faces.ViewState" value="4111543473815811212:-808789590399750244">

injected inside the form after the first click.

Don't know why the first AJAX request has no view state.  In the page, two forms are populated, doe this effect the AJAX view state?
