Examples of org.apache.struts2.views.freemarker.FreemarkerResult

org.apache.struts2.views.java.Attributes
Renders a view using the Freemarker template engine.
The FreemarkarManager class configures the template loaders so that the template location can be either
- relative to the web root folder. eg /WEB-INF/views/home.ftl
- a classpath resuorce. eg /com/company/web/views/home.ftl
This result type takes the following parameters:
- location (default) - the location of the template to process.
- parse - true by default. If set to false, the location param will not be parsed for Ognl expressions.
- contentType - defaults to "text/html" unless specified.
- writeIfCompleted - false by default, write to stream only if there isn't any error processing the template. Setting template_exception_handler=rethrow in freemarker.properties will have the same effect.
Example:
```
  <result name="success" type="freemarker">foo.ftl</result>  
```

                    }
                    // no wait result? hmm -- let's try to do dynamically put it in for you!


                    //we used to add a fake "wait" result here, since the configuration is unmodifiable, that is no longer
                    //an option, see WW-3068
                    FreemarkerResult waitResult = new FreemarkerResult();
                    container.inject(waitResult);
                    waitResult.setLocation("/org/apache/struts2/interceptor/wait.ftl");
                    waitResult.execute(actionInvocation);


                    return Action.NONE;
                }


                return WAIT;
