Hi,

I got custom authors component from the predesessors wich started to show followin error message in the Studio - Components - Preview interface:

 

Freemarker template 'preview' processing failed:
InvalidReferenceException:The following has evaluated to null or missing:
==> env.context.message  [in template "preview" at line 1, column 6]

What can I do fix the error? Code of the custom component:

    env variables work respective to page. This variable is not for studio. It will work on forum topic page without any error. Please include this component in forum topic page or forum message page.

    If you want to test in studio do something like this

     

    (env.context.message.id)!'19'

    That way if env.context.message is null, it wil set it to whatever you want (my example is 19.
