I'm trying to figure out how iterate over a collection of parameters to pump
into a text tag. This is what I would like to do:
<s:text name="%{eventtype.i18nkey}">
<s:iterator value="messageParameters">
<s:param><s:property/></s:param>
</s:iterator>
</s:text>
But it blows up and writes some stuff to the tomcat logs that appears to
suggest I'm using the tag wrong ;)
java.lang.NullPointerException
