Another <s:url> quirk:
In a jsp firstPage.jsp residing in namespace /first if you use a <s:uri>
tag to create an action url for action go-to-second-page om
namespace /second S2 gives a warning
No configuration found for the specified action:
'/second/go-to-second-page.action' in namespace: '/first'
and fails to find the action.
In short,
<s:form action="go-to-second-page" namespace="/second" >
...
</s:form>
is not equivalent to
<s:url id="myURL" action="go-to-second-page" namespace="/second"
includeContext="false" />
<s:form action="%{myURL}" >
...
</s:form>
