Ajax method firing twice from listener?

[Tbaseflug]

I have a listener tied to two radio buttons - for some reason - when I check one - the listener/ajax method seems to fire twice - once for each radio?

<div id="divOnToolbar2" style="position: absolute; top: 2; left: 0;">


<br />


<div style="padding-left: 405px;">


<ext:Radio runat="server" ID="rb0" BoxLabel="Standard Contracts" Checked="true" GroupName="filter">


<Listeners>


<Check Handler="#{hdnType}.setValue('0');Coolite.AjaxMethods.ContractsParentRefresh();" />


</Listeners>


</ext:Radio>










<div id="divOnToolbar3" style="position: absolute; top: 2; left: 0;">


<br />


<div style="padding-left: 525px;">


<ext:Radio ID="rb1" runat="server" BoxLabel="Pro Forma Contracts" GroupName="filter">


<Listeners>


<Check Handler="#{hdnType}.setValue('1');Coolite.AjaxMethods.ContractsParentRefresh();" />


</Listeners>


</ext:Radio>
