Some attributes of the Struts tags require to forse OGNL to evaluate a value. Especially the <s:radio> tag when # is referenced. According to the doc none of the attributes are evaluated. So if you want to use OGNL expression in the tag attribute you have to forse OGNL.

How to preset the value of the <s:radio> tag

<s:radio name="rentalReason" style="font-weight: normal; padding: 2px; word-wrap: break-word;"      value="%{#frm.rentalReason}" list="%{#srr}" listKey="lookupTitle" listValue="lookupTitle" /><br/>
