[jira] Commented: (WW-2528) Jsr168Dispatcher - Could not execute
action
[ https://issues.apache.org/struts/browse/WW-2528?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=43454#action_43454 ]
Mike Gardiner commented on WW-2528:
-----------------------------------
After looking into this problem a little further I am getting a null returned where a null (according to the comments) should not be returned with commented out code. This is in the following xwork 2.1.1 code.
com.opensymphony.xwork2.ActionContext
/**
* Returns the ActionContext specific to the current thread.
*
* @return the ActionContext for the current thread, is never <tt>null</tt>.
*/
public static ActionContext getContext() {
ActionContext context = (ActionContext) actionContext.get();
// Don't do lazy context creation, as it requires container; the creation of which may
// precede the context creation
//if (context == null) {
// ValueStack vs = ValueStackFactory.getFactory().createValueStack();
// context = new ActionContext(vs.getContext());
// setContext(context);
//}
return context;
}
