DataGrid itemrenderer getting issue while scroll
<p>I am using radio button inside spark datagrid as following way.</p>

<pre><code>&lt;s:DataGrid dataProvider="{arrList}" &gt;
&lt;s:columns&gt;
&lt;mx:ArrayList&gt;
&lt;mx:source&gt;
    &lt;s:GridColumn width="90" headerText="radio"&gt;
     &lt;s:itemRenderer &gt;
     &lt;fx:Component&gt;
        &lt;s:GridItemRenderer&gt;
                &lt;fx:Script&gt;
                &lt;![CDATA[
                    override public function set data( value:Object ) : void 
                    {
                        super.data = value;
                        rdId.group=outerDocument.rbgGroup;
                    }
                ]]&gt;
                &lt;/fx:Script&gt;
          &lt;s:RadioButton id="rdId" /&gt;
        &lt;/s:GridItemRenderer&gt;
        &lt;/fx:Component&gt;
        &lt;/s:itemRenderer&gt;
    &lt;/s:GridColumn&gt;

     &lt;s:GridColumn headerText="Name" dataField="name" /&gt;
    &lt;/mx:source&gt;
  &lt;/mx:ArrayList&gt;
&lt;/s:columns&gt;
&lt;/s:DataGrid&gt;
</code></pre>

<p>I have created group for radiobutton as i want any one of selected.</p>

<pre><code>&lt;s:RadioButtonGroup id="rbgGroup" /&gt;
</code></pre>

<p>This working fine. But, if i select any radio like first and scroll then it will select another radio button automatically and first selected removed.</p>

<p>I have checked many other post like <a href="https://stackoverflow.com/questions/22223551/checkbox-itemrenderer-in-datagrid-got-selected-unselected-while-scrollling-in-fl">this</a> but that doesn't seems work.</p>

<p>Issue occurred only when i scroll. <br>
Any help would greatly appreciated. </p>
