I think I figured it out.
In the testpage.jsp of his example he has this s:form tag:
{code:XML}
<s:form id="testform"
action="TestPage.action?field1=%{field1}&field2=%{field2}">
{code}
Note the action="TestPage.action..."
If you then do not have default-action-ref in struts.xml you will get the
form tag rendered as
form id="testform" name="testform" action="TestPage.action" method="post"
But if you remove the .action part (e.g. action="TestPage?field1..." then
it does not matter if you have the default-action-ref in struts.xml. You
get the correct form output of:
action="/formtest-0.0.1-SNAPSHOT/TestPage.action?field1=111&amp;field2=222
(which includes the double amp which I know how to fix by a change in
ServletUrlRenderer)
My guess is that since TestPage.action does not match a configured action
Struts is treating that as a URI path and not an action. Struts is ignoring
the query string parameters if no default-action-ref is included. If a
default-action-ref is included in struts.xml then the query string
parameters are included.
Try some testing with action="TestPage.action..." in the s:form tag and with
default-action-ref included and not included in struts.xml
