    Custom Filtering with Selectonemenu

    Ashok Chittela Newbie

      I am trying to filter the data table based on the values selected in the selectbox. I have around 10000 records in datatable, to make rendering faster I am using SerializableDataModel and i implemented logic in walk() method and Modify() method.

      I am able to filter the data table with the text box values but, i am not able to use the select box filter in this scenario. How can i get column name of the select box and the selected value and it to the filterMap in the modify method ?

      I tried filter expression but, it's not working in this scenario.



      Walk() method:


          public void walk(FacesContext context, DataVisitor visitor, Range range,
                           Object argument) throws IOException {
              // This is method we have to populate a data for DataTable
              // Range parameter provides the firstRow value and no. of rows value
              this.firstRow = ((SequenceRange) range).getFirstRow();
              this.numberOfRows = ((SequenceRange) range).getRows();
              List<CustomerList> cList = getCustomerList(this.firstRow,
                      this.numberOfRows.intValue(), this.sortField, this.ascending);
              System.out.println("customerList in walk method:" + cList.size());
              this.totalRows = new Integer(displayCustomerListOne.size());
              System.out.println("displayCustomerListOne.size" + this.totalRows);
              wrappedKeys = new ArrayList<Integer>();
              if (!cList.isEmpty()) {
                  for (CustomerList item : cList) {
                      System.out.println("item.getAvIdPk()" + item.getAvIdPk());
                      wrappedData.put(item.getAvIdPk(), item);
                      // Once data populated to wrappedKeys and wrappedData call the
                      // process method using visitor parameter
                      visitor.process(context, item.getAvIdPk(), argument);


      Modify() method:


          public void modify(List<FilterField> filterFields,
                             List<SortField2> sortFields) {
              String expressionStr = null;
              ExtendedFilterField extendedFilterField = null;
              String value = null;
              Expression filterExpression = null;
              if (null != sortFields && !sortFields.isEmpty()) {
                  SortField2 sortField2 = sortFields.get(0);
                  Expression sortExpression = sortField2.getExpression();
                  String expressionString = sortExpression.getExpressionString();
                  if (!sortExpression.isLiteralText()) {
                      expressionString = expressionString.replaceAll(
                              "[#|$]{1}\\{.*?\\.", "").replaceAll("\\}", "");
                  this.sortField = expressionString;
                  if (sortField2.getOrdering() == Ordering.ASCENDING) {
                      this.ascending = true;
                  } else if (sortField2.getOrdering() == Ordering.DESCENDING) {
                      this.ascending = false;
              if (filterFields != null && !filterFields.isEmpty()) {
                  for (FilterField filterField : filterFields) {
                      if (filterField instanceof ExtendedFilterField) {
                          extendedFilterField = (ExtendedFilterField) filterField;
                          value = extendedFilterField.getFilterValue();
                          if (value != null && !value.equals("")) {
                              filterExpression = extendedFilterField.getExpression();
                              System.out.println("filterExpression "+filterExpression);
                              expressionStr = filterExpression.getExpressionString();
                              if (!filterExpression.isLiteralText()) {
                                  expressionStr = expressionStr.replaceAll(
                                          "[#|$]{1}\\{.*?\\.", "").replaceAll("\\}",
                              filterMap.put(expressionStr, value);

          The showcase filtering sample uses a selectOneMenu, have you tried comparing your impl to that?

            I tried it but it didn't worked. All other filters are working fine, only the one with select box is not working.

            Some how the filterMap doesn't contain the select box value.


            I am using richfaces 3.3.4


            <rich:column filterValue="#{item.filterChangeType}" id="col_2"

                             filterExpression="#{fn:containsIgnoreCase(dataTableItem.changeTypeStatus, item.filterChangeType)}">

                             <f:facet name="header">


                                     <h:outputText value="ChangeTypeStatus " />

                                     <h:selectOneMenu value="#{item.filterChangeType}">

                                         <f:selectItems value="#{item.filterCts}" />

                                         <a4j:support event="onchange" reRender="data , pg" ajaxSingle="true"

              ignoreDupResponses="true" requestDelay="700"/>                           




                             <h:outputText id="cl_2" value="#{dataTableItem.changeTypeStatus}" />

              I got it working. As i am using SerializableDataModel, i wrote the select box filtering logic in walk method and it's working fine.
