It turns out this particular NPE was due to user error/misconfiguration. I'm trying to slowly transition my S1 app to S2 and started by replacing the date inputs with the datepicker tag. Unfortunately I had not added the following to my web.xml:
<filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> As soon as I did that (and added some other min libs/config files mentioned in http://struts.apache.org/2.x/docs/simple-setup.html) I was able to successfully render the tag.

Is there a showcase example or other test that demonstrates the problem, so that we will know when it's fixed? If not, the first step is to add one. We may need to setup a showcase module along the lines of the Struts 1 taglib exercises to handle reports like this. -Ted.
