The edit JSP page does not appear...

Question

Hi!
I make a simple JSF application, I would like to show a DB table in a h:dataTable component and edit a given row after click, but the edit JSP page does not appear. I click the on link in the table, but the list is loaded again and not the edit page...:(
(no exception in application server console)
Please help me!
my code:
**************************************** listmydata.jsp***************************
               <h:dataTable
                         value="#{myBean.myDataList}"
                         var="myDataItem"
                         binding="#{myBean.myDataTable}"
               >
                    <h:column>
                         <f:facet name="header">
                              <h:outputText value="Ajdi"/>
                         </f:facet>
                         <h:commandLink action="#{myBean.editMyData}">
                              <h:outputText value="#{myDataItem.id}"/>
                         </h:commandLink>

Answer 1

I have put his lines in the faces-config.xml and now it works:
     <navigation-rule>
          <from-view-id>*</from-view-id>
          <navigation-case>
               <from-outcome>editmydata</from-outcome>
               <to-view-id>editmydata.jsp</to-view-id>
          </navigation-case>
     </navigation-rule>
     <navigation-rule>
          <from-view-id>*</from-view-id>
          <navigation-case>
               <from-outcome>listmydata</from-outcome>
               <to-view-id>listmydata.jsp</to-view-id>
          </navigation-case>
     </navigation-rule>
I don't understand, that I define the next JSP page in the bean java file, which must be shown, but I must define this in the faces-config.xml as well.
for example:
     public String editMyData() {
          myDataItem = (MyData)getMyDataTable().getRowData();
          return "editmydata";
is it right or Do I make a mistake somewhere?
