public class FormFormatterInterceptor extends AbstractInterceptor

Struts 2 Interceptor used by view Actions for writing formatted versions of forms onto the Value Stack, so they're displayed instead of the unformatted form, using any conversion annotations on form fields. Such forms must implement FormattableForm. Does not apply to injected forms as its conversion errors are copied.

Interceptor parameters:

disabled
If true, all processing for this action is disabled. Defaults to false.

Extending the interceptor:

The following methods can be overridden :-

makeFormFormatLibrary
Creates helper that formats form.
makePolicyLookup
Creates helper that finds policy implementation from the annotation that configures it.

Example code:

 <action name="someAction" class="com.examples.SomeAction">
     <interceptor-ref name="annotationValidation"/>
     <interceptor-ref name="validation"/>
     <interceptor-ref name="formFormatter"/>
     <result name="success">good_result.ftl</result>
 </action>
