Strange namespace/action scenario

[stanlick <st...@gmail.com>]

Is there a limitation on when/where you can use the <s:submit..> tag to
invoke action/methods in a namespace?   


This works:
<s:form action="gradeQuiz" namespace="quiz" method="score">
<s:submit key="gradeMe"/>


This does not:
<s:form>
<s:submit key="gradeMe" action="gradeQuiz" method="score"/>

I avoid using the method attribute of submit.  The problem is that it 
includes a special prefix on the submit's paramater that the default 
action mapper detects, strips and selects that target method of your 
action.  That's fine and quite nice, however, XML validation works on 
the action name only and doesn't know you're calling a special method, 
so it may run the wrong validation task or skip validation entirely. 

My preference is to use wildcards so the action name contains the method 
name.

<s:form action="gradeQuiz" namespace="quiz">
<s:submit key="gradeMe" action="gradeQuizScore"/>

where the action is defined as
  <action name="grateQuiz*" method="{1}" ...

In this case, the action attribute of the form is completely ignored and 
each button can point to a different action and method in the namespace.

I don't recall whether AnnotationValidation allows you to run different 
validation on different methods in the same action (it never used to 
work). If that works now the problem is avoided.

I agree it's confusing.  I think it goes back to early versions of 
webwork and that's the way it works. I think the struts2 has moved on 
but the tags are much the same.
When I've needed to use a different namepace for a button I've used 
javascript to change the action of the form prior to submit.

Alright!  In my pursuit of a solution, I blew past the fact that the method
attribute of the <s:form../> tag is the HTTP method!  Struts 2 does such a
nice job of lifting you out of the HTTP API's that I actually considered
method to be uhhhhhhhhh...... the method!

Anyways, I am still a bit confused as to why the attributes need to be
distributed across the two tags to get this to work correctly.  It seems
like maybe the namespace should be an attribute of the submit tag or else
the action-method an attribute of the form!  The only error I was seeing had
to do with the goofy ParametersInterceptor<sp?> and it had me chasing my
tail far too long!  Far too long!!!


Here is the current solution:
<s:form  action="gradeQuiz" namespace="quiz">
<s:submit key="gradeMe" method="score"/>
