Are there any attributes to pre select some radio button in tag on page lodads

<h:selectOneRadio id="Radios"
    value="#{pc_ClosureDecision.closureDetails.approvalDateSelected}"
    layout="lineDirection" onclick="check_Date()">
     <f:selectItem itemValue="now" itemLabel="Now" />
     <f:selectItem itemValue="later" itemLabel="Resolve Later" />
</h:selectOneRadio></td>

Initialize #{pc_ClosureDecision.closureDetails.approvalDateSelected} with a value of "now" (in the Java code, or by injection in your faces-config.xml).
