[flexcoders] How to count lines of a DataGrid inside a Repeater ?

[Paul Barbieux]

Hi;

I have a DataGrid inside a Repeater:
I try to adjust the height of my DataGrid depending on the number of
lines provided by my DataProvider  (bijslagLines is a XMLList).
How can I count the number of elements provided by my DataProvider in
this case ? I wrote this code, but sometimes it send errors ("Error:
Repeater is not executing.    at mx.core::Repeater/get currentIndex()
...").

<mx:Repeater id="REPEATKIND" dataProvider="{bijslagLines}">
    <mx:Panel styleName="panelNoHeader">
       <mx:LinkButton label="[EMAIL PROTECTED]" />
       <mx:DataGrid id="KINDTABLE"
dataProvider="{REPEATKIND.currentItem.line}"
            
rowCount="{KINDTABLE[REPEATKIND.currentIndex].dataProvider.length}">
          <mx:columns>
             <mx:DataGridColumn dataField="maand052005" />
             <mx:DataGridColumn dataField="maand062005" />
             ...
          </mx:columns>
       </mx:DataGrid>
    </mx:Panel>
</mx:Repeater>

Here is the content of bijslagLines:
