p:dataTable (row selection) selection and pe:inputNumber not working

Question

I have a <p:dataTable > which is updated from a button and is also filled. The data is displayed correctly. But the PROBLEM is that when I click/select any row, NO RESPONSE; previously while being clicked, the row was highlighted, now-> no highlight. I have done this type of design many times but this time the <p:dataTable> is behaving weirdly. I cannot find the root of problem.

My XHTML snippet for table is :

<p:dataTable id="tblSales" rowIndexVar="rowsn"
             paginator="true" value="#{invSaleMB.dummyList}"
             var="saleObj" selectionMode="single"
             selection="#{invSaleMB.dummySaleObj}"
             rowKey="#{saleObj.item.itemTypeId}">

    <p:column headerText="#">
        <h:outputLabel value="#{rowsn+1}" />
    </p:column>
    <p:column headerText="Name">
        <h:outputLabel value="#{saleObj.item.itemTypeName}" />
    </p:column>
    <p:column headerText="Count">
        <h:outputLabel value="#{saleObj.count}" />
    </p:column>
    <p:column headerText="Unit Price">
        <h:outputLabel value="#{saleObj.unitPrice}" />
    </p:column>
    <p:column headerText="Total Price">
        <h:outputLabel value="#{saleObj.total}" />
    </p:column>
</p:dataTable>

My backing bean is @ViewScoped.

And another component which is not responding to an update trigger is <pe:inputNumber> and value for this component is 'double'. I changed the <pe:inputNumber> to <p:inputText> and worked well and displayed accurate data.

<pe:inputNumber id="totalCost" disabled="true" value="#{invSaleMB.totCost}" />

The datatable and pe:inputNumber are on same form.

What have you changed between "before" (was working) and "now" (not working)?. You are sure "#{saleObj.item.itemTypeId}" is unique for each element of the table? More code of the page could be useful.

For pe:inputNumber to work remember to include xmlns:pe="http://primefaces.org/ui/extensions" in your html tag.
