[jira] [Comment Edited] (WW-4841) Struts2.5.12 - NPE in
DeligatingValidatorContext
[ https://issues.apache.org/jira/browse/WW-4841?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16119669#comment-16119669 ]

------------------------------------------------------------------
[~yasser.zamani] - Thank you for your reply.
I added the execute method, but it is not invoked when I have the issue with textProviderFactory not being initialized.
So, I added it in the input method of my action class as:
{code:java}
@Override
public String input() {
Iterator<URL> urls = ClassLoaderUtil.getResources("struts-default.xml", XmlConfigurationProvider.class, false);
while (urls.hasNext()) {
URL url = urls.next();
System.out.println("WW-4841: " + url);
}
return INPUT;
}
{code}
and see the below printed in logs:
{code:java}
[stdout] (default task-49) WW-4841: vfs:/D:/JBossEAP/jboss-eap-7.0/bin/content/MyApp.war/WEB-INF/lib/struts2-core-2.5.12.jar/struts-default.xml
{code}
Please let me know if you see anything wrong with this.
Thanks

> Project: Struts 2
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.5.12
> Reporter: Prasann Grampurohit
> Labels: struts2.5.12
>
> We are upgrading one of our project to Struts 2.5.12. My project setup is as mentioned in the link: https://stackoverflow.com/questions/45347478/struts2-5-12-npe-while-using-gettext-method-from-actionsupport
> When I try to submit request to action on the first page, I see NullPointerException as below. Debugged it and found that textProviderFactory is null. Tried it a several times and I see that it is intermittent. Approximately twice in 10 server restarts the textProviderFactory is initialized.
> Could you please check if I am missing any configuration? I have raised a stackoverflow for this, but haven't got any response yet - https://stackoverflow.com/questions/45483364/struts2-5-12-npe-in-deligatingvalidatorcontext
