NPE on Blogposts and (Inline) Comments displayed to user #77
Description
Upgraded Confluence Server 7.3.5 -> 7.13.2
& digital-signatures 7.0.2 -> 7.0.3
When testing to sign a macro on a blog post, a 500 xml error for a NullPointerException is displayed.
The macro did receive the signing, though.
Regular confluence pages do not exhibit this problem.
The instance contains additional plugins related to blog posts:
- Linchpin Enterprise News
- (maybe) News Teaser for Confluence
The blog post in question was regular and fully published, though.
URL's like /rest/signature/1.0/sign?key=signature.a8ac9c5ed978910021be7258321a26cc5d929985cb44553b4ee202fd92ff2c50

Nothing shows up in the server log files, apart from the stacktrace also shown to the user.
Following the last comment on #65 a clearing of the plugin cache did not help with the error being shown.
(Also note that the exception is different from #65 & #68.)
