    strange problem with datascroller, calendar, and navigation

    Kip Moore Newbie

      i'm having a strange problem where apparently the calendar control seems to be interfering with the expected behavior of the datascroller.

      i have a "master" datatable with an associated datascroller - the table has a link in each row that corresponds to a "detail" page for that given row. if you click the link, the application is supposed to navigate to that detail page.

      so the user starts by viewing the "master" datatable, and starts viewing on page 1 of those results. using the datascroller, the user then clicks to page 2 of the "master" datatable and decides to view the "detail" page for row 15, let's say, which is on a different jsp page. if the user then clicks the "back" button in the browser after viewing the detail page for row 15, one would expect that would return the user to the most recently viewed page of the "master" datatable, which would be page 2. the strange thing is that if there is a calendar control on the same page as the "master" datatable then this is *not8 the case - i'm seeing that the "master" datatable will display page 1, not page 2. (in general, the user always seems to get returned back to page 1, regardless of what datatable pages have been visited.)

      if i remove the calendar control from the "master" datatable page, clicking the "back" button displays the correct page of the "master" datatable, or at least it would be the page i would expect to see. so in the case above, after viewing the "detail" page for row 15, clicking the "back" button brings the user back to the "master" page, viewing page 2 of the datatable.

      here's my code:

      Testbed.jsp ("master" page, including calendar control):

      <%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>

       <rich:dataTable id = "testbed_table"
       rows = "10"
       rules="cols"
       rowClasses="oddRow, evenRow"
       value = "#{TestbedBean.testbedTableRows}"
       binding="#{TestbedBean.data}"
       var = "test_row">
      
       <rich:column>
       <f:facet name="header">
       <h:outputText value="Column 1"/>
       </f:facet>
       <h:commandLink action="#{TestbedBean.viewTestbed2}">
       <h:outputText value="#{test_row}"/>
       </h:commandLink>
       </rich:column>
      
       <f:facet name="footer">
       <rich:datascroller id="testbed_scroller"
       for="testbed_table"

       </rich:datascroller>
       </f:facet>

      i'm seeing the same problem with Firefox 2.x and IE7, so the issue does not seem to be browser related. i'm using JBoss 4.2.2, JSF RI 1.2_08, and RichFaces 3.2.0 SR1. hopefully this description makes some sense...
