NoResult - write response in the Action

[Greg Lindholm-2]

I have a situation where I want to fully handle the result in the Action
including writing the response to the HttpServletResponse.

What's the best way to handle this so there is no further results processing
after the execute() method ends?

Is there a way to disable results processing from within the action's
execute() method?
Or, should I write a "NoResult" Result that does nothing?

I know I could write a custom Result and move all the logic from the action
to the custom result but it would be a PITA and make this situation much
more complex then it needs to be. I would have to split the logic in the
action in an artificial way and expose a bunch of internal variables just so
they could be passed to the Result and then I would have to duplicate logic
that is already available in the action super classes, etc in the result.

Dear all,

Did anyone used the doubleEmptyOption parameter of the doubleselect tag
in struts2? I have used it to create an empty option for the second
select box. However no empty option is added. In addition, the
doubleHeaderKey and doubleHeaderValue parameters are also seems has no
effect at all. I checked the doubleselect.vm file, and I haven't found
anything regarding the above three parameters. So are these not
implemented? Or I just configured wrong. I am using Struts 2.1.8.

Many thanks for any reply in advance,
Nathan

Thanks that did the trick.

Where did you learn about the NONE result? Is it documented somewhere?

Yes. See:

Hi Greg,

I first saw it in the 2.0.11 source code when trying to create a new
result type. The javadoc for it was quite helpful:

    * The action execution was successful but do not show a view. This is
      useful for actions that are handling the view in another fashion
      like redirect.

There is a reference to it in the "Result Configuration" documentation as
well:
http://struts.apache.org/2.1.8/docs/result-configuration.html

Thanks. I did see the javadoc for NONE (after you suggested using it). It
just seemed to me to be a little vague considering that NONE really is a
special case as it is the only result that is 'functional' where the others
are more like 'convention'.  In any case it certainly wasn't a place I
thought to look.

I think I will add a note to the "Result Configuration" documentation.

Hey Admins...  I don't seem to be able to edit
http://struts.apache.org/2.x/docs/result-configuration.html is there a
problem with the wiki (or is it just down for maintenance)?

Hi,

 

For a single pair of radio buttons, e.g. "Yes" or "No" without localisation,
the following jsp code seems to be straight forward and will always come out
with true/false returned to the server (localised Yes or No can be received
on the server after user have made choice, but this is not the optimal
solution I want. I want always true/false or 1/0):

 

<s:radio key="My choice" list="#{true:'Yes', false:'No'}" value="true" />

 

 

But:

 

1.         I wan to localise the Yes and No with still true/false to come
out, I failed. I have tried:

 

list="#{true:'<s:text name="yes"/>', false:'<s:text name="no"/>'}"

 

or

 

list="#{true:'${yes}', false:'${no}'}"

list="#{true:%{#yes}, false:%{#no} }}"            etc

 

hoping to access the following getter in the action class:

 

            public String getYes(){

                        return getText("yes");

            }

            public String getNo(){

                        return getText("no");

            }          

 

(Can a Struts tag embedded in another Struts tag?)

 

2.         I also failed to set the list value from action class for the
given jsp code. This is what I have tried:

 

Jsp code:

 

<s:radio key="My choice" list="yesOrNoList" value="true" />

 

a.         getter method returns a (array) list:

 

public List<String> getYesOrNoList() {

                                    String[] yesOrNoArray = {getText("yes"),
getText("no")};

            return Arrays.asList(yesOrNoArray);

}

 

b.         getter method returns a (map) list:

 

public List<Map> getYesOrNoList() {  

Map[] yesOrNoArray = {new HashMap(), new HashMap()};

            yesOrNoArray[0].put(true, getText("yes"));                  

            yesOrNoArray[1].put(false, getText("no"));                  

   return Arrays.asList(translateYesOrNoArray);

}

 

c.         getter method returns a collection:

 

public Collection<Map> getYesOrNoList() {

            Map yesOrNoArray = new HashMap();//, new HashMap()};

yesOrNoArray.put(true, getText("yes"));                      

            yesOrNoArray.put(false, getText("no"));

            return yesOrNoArray.values();

}

 

 

None of them produced the ideal result for me.

 

Could any one help please? Much appreciated.

You can't nest struts tags so you can't put a <s:text>  inside of <s:radio>
tag but you should be able to call getText().
I would try this:

<s:radio key="My choice" list="#{true:getText('yes'), false:getText('no')}"
value="true" />

This should also work:

<s:text var="yes" name="yes"/>
<s:text var="no" name="no"/>
<s:radio key="My choice" list="#{true:#yes, false:#no}" value="true" />

Greg and Samuel,

Thank you very much indeed for your quick response. Your suggestions are
indeed working!

Just out from my curiosity, would it be possible to achieve the same effect
by the code from the action class (I have got no more clue since all my
effort failed)?

The documentation (2.1.8, radio) said "If the list is a Map (key, value),
the Map key will become the option 'value' parameter and the Map value will
become the option body."

But when I tried my "map" list, the "key=value" were shown together rather
than value were shown and the key were sent to the server after choice is
made.

Cheers, Q

This should also work:

<s:text var="no" name="no"/>
<s:radio key="My choice" list="#{true:#yes, false:#no}" value="true" />

At least with String keys, it works fine:

Code in your action:
private Map<String, String> myMap = new LinkedHashMap<String, String>();
..
myMap .put("key1", "Yes");// or getText(..)
myMap .put("key2", "No");
..
public Map<String, String> getMyMap() {
        return myMap;
    }


JSP:
<s:radio list="myMap" name=".." />

My understanding was wrong - thought it has to be "List". Also did not think
about LinkedHashMap.

Tried also <Integer, String> and working fine. Guess <Boolean, String>
should also work.

Cheers!

At least with String keys, it works fine:

Code in your action:
private Map<String, String> myMap = new LinkedHashMap<String, String>();
..
myMap .put("key1", "Yes");// or getText(..)
myMap .put("key2", "No");
..
public Map<String, String> getMyMap() {
        return myMap;
    }


JSP:
<s:radio list="myMap" name=".." />

return ActionSupport.NONE?

I believe I have places where I return "null" (the value, not the string) to achieve this same purpose...
...from this discussion it sounds like I should be returning ActionSupport.NONE (which I assumed would have the value null, but actually has the value "none")...can anyone comment on which of these return values is more appropriate, or if the "correct" answer changed at some point and I missed the changelog?  I know--I'm being a bit lazy by not digging through the source to find out, but lunch (and errands) are calling me :-)

Looking at the code it appears that (null) and "none" are treated the same
and both cause results processing to be skipped.

Look for createResult() and executeResult() in DefaultActionInvocation:

Thanks!

and the annotated view:
http://svn.opensymphony.com/fisheye/browse/xwork/trunk/src/java/com/opensymphony/xwork2/DefaultActionInvocation.java?r=1851
shows that it's been that way for a long time.

What will be the view in this case ?

I mean there must be some jsp kinda thing , where the Response can be displayed !!

If the framework doesn't goes to the strust.xml file , Can we define some view in the action itself ??

I am curious , may be i am out of context for this.but  !! I donno.

I think I will add a note to the "Result Configuration" documentation.

If I understand correctly, the response will just be sent directly to the
client without going through jsp processing.

This is a special return value reserved primarily for actions that
generate their own output directly, and used to indicate that the
framework should not dispatch to any view (as the view has already been
sent to the requester).
