x:dataTable doesn't render an id per row?

Hi!

 

I know that there have been a lot of questions regarding the dataTable, but I still can't get mine to work.

 

I have a table which looks like this:

 

            <x:dataTable id="pubTable"
                         styleClass="publicationTable"
                         headerClass="publicationTable_SortHeader"
                         rowClasses="publicationTable_row1,publicationTable_row2"
                         var="publication"
                         value="#{publicationsBean.publicationModel}"
                         sortColumn="#{publicationsBean.sort}"
                         sortAscending="#{publicationsBean.ascending}"
                         preserveDataModel="true"
                         preserveSort="true">
              <h:column>
                <f:facet name="header">
                  <h:panelGroup></h:panelGroup>
                </f:facet>
                <h:graphicImage alt="#{pubmgr_messages['alt_validated']}"
                                url="">
                </h:graphicImage>
              </h:column>
              <h:column>
                <f:facet name="header">
                  <x:commandSortHeader columnName="code" arrow="true">
                    <h:outputText value="Code" />
                  </x:commandSortHeader>
                </f:facet>
                <x:commandLink action="" immediate="true" styleClass="publication_select">
                  <x:outputText value="#{publication.code}" />
                </x:commandLink>
              </h:column>
              <h:column>
                <f:facet name="header">
                  <x:commandSortHeader columnName="name" arrow="true">
                    <h:outputText value="Name" />
                  </x:commandSortHeader>
                </f:facet>
                <h:outputText value="#{publication.names['en']}" />
              </h:column>
            </x:dataTable>

 

The table is rendered to this:

 

<table id="pubForm:pubTable" class="publicationTable">
<thead>

 

<tr><th class="publicationTable_SortHeader"></th><th class="publicationTable_SortHeader"><a href="" id="pubForm:pubTable:_id11">Code</a></th><th class="publicationTable_SortHeader"><a href="" id="pubForm:pubTable:_id16">Name&#x2193;</a></th></tr></thead>
<tbody>
<tr class="publicationTable_row1"><td><img id="pubForm:pubTable:_id9" src="" alt="validate status"/></td><td><a href="" id="pubForm:pubTable:_id13" class="publication_select">testcode1</a></td><td>testname1</td></tr>
<tr class="publicationTable_row2"><td><img id="pubForm:pubTable:_id9" src="" alt="validate status"/></td><td><a href="" id="pubForm:pubTable:_id13" class="publication_select">testcode2</a></td><td>testname2</td></tr>
<tr class="publicationTable_row1"><td><img id="pubForm:pubTable:_id9" src="" alt="validate status"/></td><td><a href="" id="pubForm:pubTable:_id13" class="publication_select">testcode3</a></td><td>testname3</td></tr>
<tr class="publicationTable_row2"><td><img id="pubForm:pubTable:_id9" src="" alt="validate status"/></td><td><a href="" id="pubForm:pubTable:_id13" class="publication_select">testcode4</a></td><td>testname4</td></tr><tbody></table>

 

The publicationsBean backing bean has the following setters/getters:

 

  public DataModel getPublicationModel()
  {
    if (this.publicationModel == null)
    {
      this.publicationModel = new ListDataModel();
    }
    if (this.sortablePublications == null)
    {
      this.sortablePublications = new SortablePublicationList(loadPublications());
    }
    this.publicationModel.setWrappedData(this.sortablePublications.getPublications()); <--- so I just put a list of Publications in the DataModel
    this.publicationModel.addDataModelListener(new DataModelListener()
    {
   public void rowSelected(DataModelEvent e)
   {
    System.out.println("row selected:" + e.getRowIndex()); <----- clicking on a link in the table activates this for the whole column?!
   }
    });
    return this.publicationModel;
  }
 
  public void setPublicationModel(DataModel dataModel)
  {
    this.publicationModel = dataModel;
  }

 

  private List loadPublications()
  {
    <return a List of Publication>
  }

 

  public String getSort()
  {
    if (this.sortablePublications == null)
    {
      this.sortablePublications = new SortablePublicationList(loadPublications());
    }
    return this.sortablePublications.getSort();
  }

 

  public void setSort(String sort)
  {
    this.sortablePublications.setSort(sort);
  }

 

  public boolean isAscending()
  {
    if (this.sortablePublications == null)
    {
      this.sortablePublications = new SortablePublicationList(loadPublications());
    }
    return this.sortablePublications.isAscending();
  }

 

  public void setAscending(boolean ascending)
  {
    this.sortablePublications.setAscending(ascending);
  }

 

The sorting works, as it is I'm already quite happy with the output ;-)

 

Yet! I can't get the id of selected Publication once the commandLink is pressed as there seems to be a problem with the generated ids of each row!

 

As far as I know, each id should be something like pubForm:pubTable_0:_id13, pubForm:pubTable_1:_id13, etc...?!

 

As all my rows have the same id (see the rendered table), the DataModel's getDataRow() method always returns the last item from the row (after having iterated over the whole column it seems).

 

Does anyone know what my problem could be?

 

The master/detail example from the myfaces examples does get an id per row so I'm reckoning it's still possible.

 

I tried using <x:updateActionListener property="#{publicationsBean.selectedPublication}" value="#{publication}" />, but the problem remains as the system can't differentiate between the rows...

 

Many thanks in advance for any help!!

 

Greetings,
Kris
