when i add the code and launch, i get a white screen - no errors.  I'm able to do it in the flex libraries but not spark, here is my code (top does not work so commented out)

<s:DataGrid dataProvider="{EdsDataArray}" width="100%">

                              <s:columns>

                                        <s:ArrayList>

                                                  <s:GridColumn dataField="id"/>

                                                  <s:GridColumn dataField="NAME"/>

                                                  <s:GridColumn headerText="Remove">

                                                            <!--s:itemRenderer>

                                                                      <fx:Component>

                                                                                <mx:Button label="Delete" click=""/>

                                                                      </fx:Component>

                                                            </s:itemRenderer-->

                                                  </s:GridColumn>

                                        </s:ArrayList>

                              </s:columns>

                    </s:DataGrid>

                    <mx:DataGrid id="dg" dataProvider="{EdsDataArray}" width="100%">

                    <mx:columns>

                              <mx:DataGridColumn headerText="ID" dataField="id"/>

                              <mx:DataGridColumn headerText="NAME" dataField="NAME"/>

                              <mx:DataGridColumn headerText="Remove">

                                        <mx:itemRenderer>

                                                  <fx:Component>

                                                            <mx:Button label="Delete" click=""/>

                                                  </fx:Component>

                                        </mx:itemRenderer>

                              </mx:DataGridColumn>

                    </mx:columns>

  </mx:DataGrid>
