JDeveloper 12.2.1 Random error. AssertionFailedException: The listener cannot be null, aspectName=va

Ramjech_sdMay 17 2016 — edited May 17 2016

Hello everyone,

I downloaded the new JDeveloper version 12.2.1 and I'm having an annoying error.

Everytime I change tabs, or copy and paste variables or do any kind of actions inside the IDE, this raise up an exception.

I don“t know what it could be, so I'm hoping you can help me with this issue.
