When a selectInputDate is in a dataTable the only date value that can be set is the last rows. Once this has been set selected the selected date is populated into the other rows date inputs. Also for the other selectInputDate components you can select a date, only the last row is able to be selected. This issue does not occur with 1.7.2 SP1.

Code to replicate:

<ice:dataTable value="#{testBean.tableList}"
                           var="item">
     <ice:column>
          <f:facet name="header">
               <ice:outputText value="Column One"/>
          </f:facet>
          <ice:outputText value="#{item.itemOne}"/>
     </ice:column>
     <ice:column>
          <f:facet name="header">
               <ice:outputText value="Date"/>
          </f:facet>
          <ice:selectInputDate renderAsPopup="true"
                                                value="#{item.date}">
               <f:convertDateTime pattern="MM/dd/yyyy"
                                                   timeZone="#{testBean.timeZone}"/>
          </ice:selectInputDate>
     </ice:column>
</ice:dataTable>
