Creating yes and no switches using struts2 and freemarker

In my struts2 application, I would like to bind the boolean property (let it draw frobbed using isFrobbed () getter) on my controller with a couple of yes and no radio buttons (I know that I can use the checkbox, but for various reasons we preferred would be a clear yes and no)).

Using the checkbox, I will do something like this:

<@s.checkbox name="frobbed" label="would you like this to be frobbed?" />

However, with the switches I completely lost. I know there is a struts2 tag called "radio", but I'm not sure how it is used. For example, this does not work.

 <@s.radio name="frobbed" value="true" label="Please frob this object" /> <@s.radio name="frobbed" value="false" label="No frobbing, thanks." />

I would like this to be related to the "frobbed" value in the controller, so that, for example, when the value is true, the yes camera is automatically selected.

Any ideas?

This syntax works with FreeMarker for logical selection:

 <@s.radio label="" name="frob" list="#@ java.util.LinkedHashMap@ {true:'Frob it',false:'Leave unfrobbed'}" />

When the choice is simple Yes / No, True / False - I prefer to define in-situ options inside jsp. Sort of..

 <s:radio label="Frobbed?" list="#{true:'Frob Me',false:'Leave me Frobless'}" name="frobbed" value="%{frobbed}"></s:radio>

Typically, the <s:radio> used with a list of options (or cards). For example, with the card, the key will be the radio values ​​(for example, Boolean.TRUE and Boolean.FALSE in this case), and the value will be the label of the radio button ("Frob away", "I prefer to remain unchanged").

 <s:radio list="yesNo" name="frobbed"/>

The value of the yesNo attribute is a list or map.

(With a list, you expose an object with a label and value and use the attributes "listKey" and "listValue" <s:radio> . (IIRC))
