I need to use inplaceInput inside a table (rich:table).
The table contains many inplaceInput in any row and in different columns.

How can I detect which row/column is modified?
Somebody can post some snippet of clear code?

Below the pseudo code about my table

<rich:dataTable id="list"
    rowClasses="odd,even"
    value="#{iesimoAnno}"
    var="i"
    rowKeyVar="row">

    <rich:column>
      <f:facet name="header">
        <h:outputText value="#{messages['curriculum.peso.label']}" />
      </f:facet>

        <rich:inplaceInput
            layout="block"
            value="#{i.insegnamento.peso}"
            id="peso#{status.index}"
            required="true"
            requiredMessage="#{messages['mandatory.value.at.row']}"
            changedHoverClass="hover"
            viewHoverClass="hover"
            viewClass="inplace"
            changedClass="inplace"
            selectOnEdit="true"
            validatorMessage="#{messages['invalid.value.at.row']}">
                          
            <a4j:support
              event="onviewactivated"
              reRender="listAnno#{status.index}, messages#{status.index}"
              rendered="#{!i.modulo and !i.insegnamento.gruppo}"
             />
        </rich:inplaceInput>

    </rich:column>



    <rich:column>
      <f:facet name="header">
        <h:outputText value="#{messages['curriculum.durata.label']}" />
      </f:facet>

        <rich:inplaceInput
            layout="block"
            value="#{i.insegnamento.durata}"
            id="durata#{status.index}"
            required="true"
            requiredMessage="#{messages['mandatory.value.at.row']}"
            changedHoverClass="hover"
            viewHoverClass="hover"
            viewClass="inplace"
            changedClass="inplace"
            selectOnEdit="true"
            validatorMessage="#{messages['invalid.value.at.row']}">
                          
            <a4j:support
              event="onviewactivated"
              reRender="listAnno#{status.index}, messages#{status.index}"
              rendered="#{!i.modulo and !i.insegnamento.gruppo}"
             />
        </rich:inplaceInput>

    </rich:column>

</rich:dataTable >
