Error launching select event in a region

Question

Hi,
We are developing an application using JHeadStart and ADF Faces in JDeveloper 10.1.3.1.
Due to the size of the page code, we have splitted the page in different regions. The page has a master-detail-subdetail structure, where each subdetail has been put in a separated ADF region.
When changing the selected row in the master table, the values displayed in the detail table are refreshed. But when we do the same in the detail, no action takes place (the data in the subdetail doesn't change, and the code for the selection event listener is not executed either).
If I don't use ADF regions, the selection event listener code is executed. What could happen? On the other hand, an action event in the region is executed without problems.
Some pieces of the code:
- The include of the detail region in the main page:
<af:region id="ConcepteEco2" value="#{bindings}" regionType="cat.coec.outis.view.region.ConcepteEco2"/>- The declaration of the detail table in the region:
<af:table id="ConcepteEco2Table" styleClass="scrollable "
              value="#{ConcepteEco2CollectionModel}"
              inlineStyle="height: 120px; width:  1000px ; "                     
              rangeChangeListener="#{ConcepteEco2CollectionModel.processRangeChange}"
              selectionState="#{ConcepteEco2CollectionModel.selectedRow}"
             selectionListener="#{ConcepteEco2CollectionModel.makeCurrent}"
              disclosureListener="#{ConcepteEco2CollectionModel.hideAllDetails}"           
              varStatus="status"
              var="row" rows="#{bindings.ConcepteEco2Table.rangeSize}"
              first="#{bindings.ConcepteEco2Table.rangeStart}"
              emptyText="#{bindings.ConcepteEco2Table.viewable ? 'No hi ha dades.' : 'Accés Denegat.'}"
              binding="#{ConcepteEco2CollectionModel.table}"
              partialTriggers="TipusCctEcoTable"          >- The declaration of the table selection facet:
<!-- DEBUG:BEGIN:TABLE_SELECTION : outis/pageComponent/tableSelection.vm, nesting level: 11 -->
  <f:facet name="selection">
        <af:tableSelectOne disabled="#{ConcepteEco2CollectionModel.newRow}"
        autoSubmit="true" id="ConcepteEco2SelectOne"
        onclick="javascript:selectCurrentRow('ConcepteEco2:ConcepteEco2',this);">
<!-- DEBUG:BEGIN:DUPLICATE_ROW_BUTTON : outis/button/duplicateRowButton.vm, nesting level: 12 -->
<!-- DEBUG:END:DUPLICATE_ROW_BUTTON : outis/button/duplicateRowButton.vm, nesting level: 12-->
    </af:tableSelectOne>
      </f:facet><!-- DEBUG:END:TABLE_SELECTION : outis/pageComponent/tableSelection.vm, nesting level: 11--> Any help would be appreciated,

hi,
in your datagrid call use the property itemClick.
e.g <mx:DataGrid id="DG" dataProvider="{some provider"}
itemClick"myFunction())">
then in your script you can declare the function myFunction
to get column values of the selected row, use
DataGrid.selectedItem.ColumnDatafield
so for the above datagrid with a column name and
dataField=fullName i can use
DG.selectedItem.fullName
HTH
