That happens sometimes, I apologize for that.

Absolutely. HMAC safe too. I suggest using DHTML:

<f:form.hidden property="city" id="someid" />
<ul>
<f:for each="{cities}" as="city">
  <li><a data-value="{city.id}" href="javascript:;" onclick="jQuery('#someid').val(jQuery(this).attr('data-value');">{city.name}</a></li>
</f:for>
</ul>

...but you may want to use another way of DHTML'ing the above. Possibly also add a check for the selected city and set a class for the relevant city link for highlighting.

You should avoid doing that at all cost, IMHO.
