    search function using filterBy

    Zia Sen Newbie

      I´m trying to implement a search function using the filterBy attribute like in this example: http://livedemo.exadel.com/richfaces-demo/richfaces/filteringFeature.jsf?c=filtering

      But it doesn´t work! Can somebody tell me if this example isn`t right? I wonder why there is no inputtext in the code where i can type in although the page contains the input-fields. I changed the outputtext into inputtext but nothing happens when i type something in!

      I haven´t found another example which uses the filterBy functionality. Does anyone know a good page with some examples or tutorials for implementing a search or filtering method?

      This is the source code from this page above

      <ui:composition xmlns="http://www.w3.org/1999/xhtml"

      xmlns:ui="http://java.sun.com/jsf/facelets"

      xmlns:h="http://java.sun.com/jsf/html"

      xmlns:f="http://java.sun.com/jsf/core"

      xmlns:a4j="http://richfaces.org/a4j"

      xmlns:rich="http://richfaces.org/rich">

      <h:form>

      <rich:dataTable value="#{capitalsBean.capitals}" var="cap">

      <f:facet name="header">

      <rich:columnGroup>

      <rich:column colspan="2" >

      <h:outputText value="Filtering Example"/>

      </rich:column>

      <rich:column breakBefore="true">

      <h:outputText value="State Name"/>

      </rich:column>

      <rich:column>

      <h:outputText value="State Capital"/>

      </rich:column>

      </rich:columnGroup>

      </f:facet>

      <rich:column filterBy="#{cap.state}" filterEvent="onkeyup">

      <f:facet name="header">

      <h:outputText value=" " title="Hack due to bug. Shuold be remoevd till release"></h:outputText>

      </f:facet>

      <h:outputText value="#{cap.state}"/>

      </rich:column>

      <rich:column filterBy="#{cap.name}" filterEvent="onkeyup">

      <h:outputText value="#{cap.name}"/>

      </rich:column>

      </rich:dataTable>

      </h:form>

      </ui:composition>

          in this demo code - built in filtering used. So there is inplaces in headers generated automatically.

          If you need to implement external filtering. (with external filtering field and serch button ) - explore second tab of filtering demo page.

            Thx! But I still have a problem with external filtering. When I type in the first time, it disappears after 500 ms and then I can type in whatever I want and nothing happens.

            This is my View:

            And this is my FilterMethod as discribed here http://livedemo.exadel.com/richfaces-demo/richfaces/filteringFeature.jsf;jsessionid=FB3596EDBFA5083818701D1BC1B103B1:

             public boolean filterPG(Object current) {
            
             Produktgruppe currentPG = (Produktgruppe)current;
             System.out.println(currentPG.getBezeichnung());
             if (filterValue.length()==0) {
             return true;
             }
             if (currentPG.getBezeichnung().toLowerCase().startsWith(filterValue.toLowerCase())) {
             return true;
             }else {
             return false;
            
             }
            
             }

              Has nobody any ideas? Does anybody know an example with filtering? This is very important for me!!
