Newbie - form:radio tag

[Heiko Roth]

I am migrating struts code from version 0.5 to the november 17, build of
struts.  In particular, I cannot get the radio button form tag to work.
Does anyone have an example of the code for a radio button?  Here is what I
currently am trying:

              <struts:radio name="formName" property="propertyName"
value="0"/>

In the docs, there is no mention of the dataType that the property must be.
Must it be a string??

Thanks,
