[jira] [Commented] (WW-4045) Null Pointer Exception on DefaultActionValidatorManager

["Lukasz Lenart (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/WW-4045?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13660492#comment-13660492 ] 

Lukasz Lenart commented on WW-4045:
-----------------------------------

It must be something else, {{DefaultFileManger#loadFile}} can handle null - it will return null in that case and the rest of the code also can handle null.

Could you prepare a working example, Maven based? Or instruct me how reproduce that NPE?

> With the change implemented on WW-3850, I think the missing piece is that if the validatorFileCache does not contain the fileName being modified, that the line  is = fileManager.loadFile(fileUrl); is still being executed which will still result in a null pointer exception.
