-----------------------------------
Yes - 2.3.24, but you are mixing different versions of Xwork:
{code:xml}
<dependency>
<groupId>com.opensymphony</groupId>
<artifactId>xwork</artifactId>
<version>2.1.3</version>
</dependency>
...
<dependency>
<groupId>org.apache.struts.xwork</groupId>
<artifactId>xwork-core</artifactId>
<version>2.3.24</version>
</dependency>
{code}
> FreemarkerManager class throws null pointer exception

> Am getting a null pointer error in the FreemarkerManager class. It occurs in
> the setContainer method. The code below seems to assume that getInstanceNames
> returns an empty set if there are no matches. In fact, it returns a null,
> which is legit according to the XWork doc. This occurs in Freemarker 2.3.23
> under WebLogic 12.1.3.
> {code:java}
> Map<String, TagLibrary> oldMap = new HashMap<String, TagLibrary>();
> Set<String> oldPrefixes = container.getInstanceNames(TagLibrary.class);
> for (String prefix : oldPrefixes) {
> oldMap.put(prefix, container.getInstance(TagLibrary.class, prefix));
> {code}
> Not sure if this affects the presentation of Struts2 views. Is there a
> workaround or fix?
