Using Tiles 3 in combination with Freemarker within Spring MVC. According to this unanswered post (see here http://tinyurl.com/okehanq) cause of the exception is due to "exposeSpringMacroHelpers" property not set to true.

I came across a post (see here https://ehc.ac/p/freemarker/discussion/2346/thread/7c922d1c/) which mentions using the full namespace e.g. "<#import "/org/springframework/web/servlet/view/freemarker/spring.ftl" as spring/>", which seems work for me too but haven't a clue why "/spring.ftl" fails.

Exception

Config Class

@Bean
public UrlBasedViewResolver tilesViewResolver(){
UrlBasedViewResolver urlBasedViewResolver = new UrlBasedViewResolver();
urlBasedViewResolver.setViewClass(FreemarkerTilesView.class);
return urlBasedViewResolver;
}

@Bean
public TilesConfigurer tilesConfigurer(){
TilesConfigurer tilesConfigurer = new TilesConfigurer();
tilesConfigurer.setCompleteAutoload(true);
return tilesConfigurer;
}

Template (default.ftl)

<html lang="en">
<#import "/spring.ftl" as spring />
...
</html>
Sample Project

I have attached a small project to demonstrate the problem.
