Thymeleaf Unescaped JavaScript Inlining

Question

How can I get unescaped JavaScript inlining output with Thymeleaf 3.0.x? Escaped inlining works just fine. Example:

pom.xml

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
<dependency>
  <groupId>org.thymeleaf</groupId>
  <artifactId>thymeleaf-spring3</artifactId>
  <version>3.0.3.RELEASE</version>
</dependency>

servelet:

model.addAttribute("test", "testing...");

html template:

<script th:inline="javascript">
/*<![CDATA[*/
  [[${test}]]
  [(${test})]
/*]]>*/
</script>

generated output:

<script>
/*<![CDATA[*/
  'testing...'
  [(${test})]
/*]]>*/
</script>

So, escaped expression [[ ]] works, but unescaped expression [( )] doesn't. I have a need to generate js conditionally, and there's no "easy" workaround, so this would've been very helpful. Has anyone been able to get this to work? Any help much appreciated!

I finally got it to work with Spring Boot with the following four dependencies, all four being required (I'm using the latest versions currently available):

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>    
<dependency>
    <groupId>org.thymeleaf</groupId>
    <artifactId>thymeleaf</artifactId>
    <version>3.0.3.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.thymeleaf</groupId>
    <artifactId>thymeleaf-spring4</artifactId>
    <version>3.0.3.RELEASE</version>
</dependency>
<dependency>
    <groupId>nz.net.ultraq.thymeleaf</groupId>
    <artifactId>thymeleaf-layout-dialect</artifactId>
    <version>2.1.2</version>
</dependency>

Hope this helps.
