Avoid having an action property called id

This  http://www.vitarara.org/cms/struts_2_cookbook/post_and_redirect article
about post and redirect in struts 2  explains how to redirect to a
dynamically evaluated action.


However, if I use a param which references an action property called "id",
it doesn't work. 

&lt;result type="redirect-action"&gt;
  &lt;param name="actionName"&gt;${redirectActionName}&lt;/param&gt;
  &lt;param name="namespace"&gt;/admin/holidays&lt;/param&gt;
  &lt;param name="parse"&gt;true&lt;/param&gt;
  &lt;param name="id"&gt;${id}&lt;/param&gt;
&lt;/result&gt;

But when I changed the property (and its getter and setter) to be called
"aid", it works OK:
&lt;result type="redirect-action"&gt;
  .. as above...
  ..............
  &lt;param name="id"&gt;${aid}&lt;/param&gt;
&lt;/result&gt;


Also (possibly unrelated), again with a property called id on my action,
when I use the &lt;s:url&gt; tag, it automatically adds the current value of
the action's id to the URL even if I don't want it to. The docs don't
mention that this should happen (it's annoying).

It seems as if naming an action property id should be avoided...
