Simple gant chart with parent_id

Question

Hi,
I'm trying to recreate the following project gant chart on my system
http://apex.oracle.com/pls/apex/f?p=36648:4:896508273706037::NO
I don't understand why on my side the 'chart integration' task is not having the red arrow for drill down.
What I'm doing wrong?
Many thanks in advance,
Florin
this is my table:
CREATE TABLE "GANTT_TEST"
(     "TASK_ID" NUMBER,
     "TASK_NAME" VARCHAR2(55),
     "START_DATE" DATE,
     "END_DATE" DATE,
     "STATUS" NUMBER,
     "PARENT_ID" NUMBER,
     "PLANNED" DATE,
     "PLANNED_END" DATE
I have 3 lines. 2 of them have on the PARENT_ID the TASK_ID=1

This is really a Flex question not an Islands specific one.  I don't think the displayName properity is what you want to use here.  This is the name for the entire series as it will be displayed in the legend. I think what you want is a dataTip.  You register a callback for the dataTip rendering and then fill the custom dataTip quick info.
This is an example from a bar chart, but the theory is the same:
<mx:BarChart id="barChart" dataTipFunction="dtFunc" xmlns:mx="http://www.adobe.com/2006/mxml" type="clustered" width="100%" showDataTips="true" height="100%">
     <mx:verticalAxis>
          <mx:CategoryAxis categoryField="{SalesOrd}" dataProvider="{dataSource}" />
     </mx:verticalAxis>
     <mx:series>
          <mx:BarSeries id="bsGross" xField="{grossAmt}" displayName="Gross Amount" dataProvider="{dataSource}" fill="{otdFill}" showDataEffect="{slideIn}"  />
          <mx:BarSeries id="bsNet" xField="{netAmt}" displayName="Net Amount" dataProvider="{dataSource}" fill="{rtyFill}" showDataEffect="{zoomIn}"  />          
     </mx:series>
</mx:BarChart>
private function dtFunc(hd:HitData):String {
              switch(BarSeries(hd.element).id){
                   case "bsGross":
                         return "Sales Order #: " +  hd.item.SO_ID + "\n" + FlashIsland.formatNumber(hd.item.TTL_GROSS_AMOUNT) + " " + hd.item.CURRENCY_CODE;                        
                         break;
                   case "bsNet":
                         return "Sales Order #: " +  hd.item.SO_ID + "\n " + FlashIsland.formatNumber(hd.item.TTL_NET_AMOUNT) + " " + hd.item.CURRENCY_CODE;
                         break;                   
              return "Amount";
