Not sure what the new ones are, but my Maven dependency uses version 2.1.6 of
the struts2 sitemesh plugin:
<code>
<dependency>
<groupId>org.apache.struts</groupId>
<artifactId>struts2-sitemesh-plugin</artifactId>
<version>${struts.version}</version>
</dependency>
...
<struts.version>2.1.6</struts.version>
</code>
Is there any other filter I can try?
