    ExtendedDataTable with onselectionchange support blocking re

    Kip Moore Newbie

      i think i'm having a problem with rerendering an extendedDataTable that has an <a4j:support event="onselectionchange"/> attached to it. i could be wrong about this, but i'm hoping someone can shed some light on this for me.

      simply put, i have a page with two extendedDataTables on it, in a sort of "master-detail" arrangement. selecting a row (or rows) from the "master" table will display just the selected rows in the "detail" table. this is a simple enough arrangement, and it works quite well once i add the now-functional <a4j:support event="onselectionchange"/> support.

      the problem i'm having occurs in my implementation of a "clear" button. basically, when i hit the "clear" button, i want to clear the contents of the "detail" table and return the "master" table to a state where nothing is selected - in effect, returning the page to the visual state when it was first loaded. i can get the "detail" table to rerender as expected, but the "master" table will not rerender.

      my jsp:

      <f:view>
       <a4j:form id="test_form">
      
       <h:outputText value="Master table"/>
       <rich:extendedDataTable rowKeyVar="rkv"
       height="140px"
       width="280px"
       id="master_table"
       value="#{TestbedBean.masterValues}"
       var="master"
       sortMode="single"
       selectionMode="multi"
       binding="#{TestbedBean.masterTable}"
       selection="#{TestbedBean.masterSelection}">
      
       <rich:column width="60px" id="master_id_col" label="ID" sortable="true" sortBy="#{master}">
       <f:facet name="header">
       <h:outputText id="master_id_col_hdr_txt" styleClass="headerText" value="ID" />
       </f:facet>
       <h:outputText id="master_id_text" value="#{master}"/>
       </rich:column>
       <a4j:support id="a4j_support_master" reRender="detail_table" event="onselectionchange" />
       </rich:extendedDataTable>
      
       <br>
      
       <h:outputText value="Detail table"/>
       <rich:extendedDataTable rowKeyVar="rkv"
       height="140px"
       width="280px"
       id="detail_table"
       value="#{TestbedBean.detailValues}"
       var="detail"
       sortMode="single"
       selectionMode="multi"
       binding="#{TestbedBean.detailTable}"
       selection="#{TestbedBean.detailSelection}">
      
       <rich:column width="60px" id="detail_id_col" label="ID" sortable="true" sortBy="#{detail}">
       <f:facet name="header">
       <h:outputText id="detail_id_col_hdr_txt" styleClass="headerText" value="ID" />
       </f:facet>
       <h:outputText id="detail_id_text" value="#{detail}" />
       </rich:column>
       </rich:extendedDataTable>
      
       <a4j:commandButton id="clear_tables"
       immediate="true"
       value="Clear Tables"
       action ="#{TestbedBean.clearTables}"
       reRender="master_table,detail_table"/>
      
       <rich:messages id="messages" ajaxRendered="true" globalOnly="true" styleClass="font_size_eight_point" errorClass="red" />
      
       <br>
       <br>
      
       <a4j:log popup="false" level="ALL"/>
       </a4j:form>
      </f:view>
      


      my backing bean:

      public class TestbedBean
      {
       private static Logger logger = Logger.getLogger(TestbedBean.class.getName());
      
       protected SimpleSelection masterSelection = new SimpleSelection();
       protected UIDataTable masterTable;
      
       protected SimpleSelection detailSelection = new SimpleSelection();
       protected UIDataTable detailTable;
      
       public List getMasterValues()
       {
       return new ArrayList<String>(Arrays.asList(new String[]{"1", "2", "3", "4", "5", "6", "7", "8", "9", "10"}));
       }
      
       public List getDetailValues()
       {
       ArrayList<Object> retval = new ArrayList<Object>();
      
       Iterator<Object> iterator = masterSelection.getKeys();
      
       while (iterator.hasNext())
       {
       Object key = iterator.next();
      
       masterTable.setRowKey(key);
      
       if (masterTable.isRowAvailable())
       {
       retval.add(masterTable.getRowData());
       }
       }
      
       return retval;
       }
      
       public String clearTables()
       {
       masterSelection = new SimpleSelection();
       masterTable = null;
      
       detailSelection = new SimpleSelection();
       detailTable = null;
      
       return "";
       }
      
       public SimpleSelection getMasterSelection()
       {
       return masterSelection;
       }
      
       public void setMasterSelection(SimpleSelection masterSelection)
       {
       this.masterSelection = masterSelection;
       }
      
       public UIDataTable getMasterTable()
       {
       return masterTable;
       }
      
       public void setMasterTable(UIDataTable masterTable)
       {
       this.masterTable = masterTable;
       }
      
       public SimpleSelection getDetailSelection()
       {
       return detailSelection;
       }
      
       public void setDetailSelection(SimpleSelection detailSelection)
       {
       this.detailSelection = detailSelection;
       }
      
       public UIDataTable getDetailTable()
       {
       return detailTable;
       }
      
       public void setDetailTable(UIDataTable detailTable)
       {
       this.detailTable = detailTable;
       }
      
      }
      


      the reason i think that this might be a bug is that the <a4j:log> reports a warning and a few errors when i click on "clear tables". here they are:

      ...
      warn[15:29:00,234]: Node for replace by response with id test_form:master_table:0 not found in document
      ...
      error[15:29:00,236]: New node for ID test_form:master_table:master_id_colmenu_menu_script is not present in response
      ...
      error[15:29:00,236]: New node for ID test_form:master_table:j_id32_menu_script is not present in response
      ...
      


      i'm using a recent (october 2, i believe) nightly build of richfaces 3.3.0. any help would be much appreciated!
