I am using ww2 so there is no webwork.util.counter class. I don't know how
it worked in ww1 but in ww2 the Iterator tag will only use a Collection,
Array, or a Map. But you have shown the kind of thing I would like to be
able to do.

What you want to do (I think) is:
<ww:bean name="'webwork.util.Counter'" id="'days'">
<ww:param name="'first'" value="'1'"/>
<WW:param name="'last'" value="'31'"/>
<ww:iterator>
<option value="<ww:property/>" <ww:if test=". ==
../../yourActionAttribute">selected</ww:if>><ww:property/></option>
</ww:iterator>
</ww:bean>
The above is untested, though.
