Date Filter uses unknown property by default, doesnt work

Question

Created a filterable and sortable table by dragging and dropping in VO from a AM. While it automatically sets the appropriate properties for filtering, and for non-date fields it works fine, for dates always "no row are found," even if I specifically choose a valid date where rows should return.
I noticed in the property inspector, the inputdate value in the column's facet filter is set to an invalid value (by default when dragged and dropped!). In the property inspector, the value is outlined in orange (value=#{vs.filterCriteria.trSentOnDate}, populated by default), and the tooltip states "filterCriteria is an unknown property."
Here's a snippet of the table def
        <af:table value="#{bindings.RequisitionsAllVO11.collectionModel}"
                        var="row"
                        rows="#{bindings.RequisitionsAllVO11.rangeSize}"
                        emptyText="#{bindings.RequisitionsAllVO11.viewable ? 'No data to display.' : 'Access Denied.'}"
                        fetchSize="#{bindings.RequisitionsAllVO11.rangeSize}"
                        rowBandingInterval="0"
                        filterModel="#{bindings.PoRequisitionHeadersAllVO1Query.queryDescriptor}"
                        queryListener="#{bindings.PoRequisitionHeadersAllVO1Query.processQuery}"
                        filterVisible="true" varStatus="vs"
                        selectedRowKeys="#{bindings.RequisitionsAllVO11.collectionModel.selectedRow}"
                        selectionListener="#{bindings.RequisitionsAllVO11.collectionModel.makeCurrent}"
                        rowSelection="single"
                        binding="#{backingBeanScope.backing_browseReqsPOs.t3}"
                        id="t3">
                <af:column sortProperty="SentOnDate" filterable="true"
                           sortable="true"
                           headerText="#{bindings.RequisitionsAllVO11.hints.SentOnDate.label}"
                           id="c26">
                  <f:facet name="filter">
                    <af:inputDate value="#{vs.filterCriteria.SentOnDate}"
                                  id="id2"/>
                  </f:facet>
                  <af:outputText value="#{row.SentOnDate}" id="ot20">
                    <af:convertDateTime pattern="#{bindings.RequisitionsAllVO11.hints.SentOnDate.format}"/>
                  </af:outputText>
                </af:column>BTW, I looked at the ADF RC Demos, and I noticed that for the filterable table demos, the date filter isn't enabled.

Answer 1

We're getting there.
New error now. I neglected to set the attribute Format and Format Type. I set those in the VO (Simple Date and MM/dd/yyyy, respectively), and now I get a nullPointerException.
I hit enter after entering a date, and a popup shows the following:
java.lang.NullPointerException
