Form Comment Plugin

[gvoto]

Hi,

I downloaded and installed the plug-in to insert comments in a form of fabrik
I activated the plugin and configured to use Jcomment in the form plugin configuration.

But if I open the form I have an error:

Fatal error: Call to undefined method PlgFabrik_FormComment :: getModel () in plugins / fabrik_form / comment / Comment.php on line 127

I did not find much information about.
I need to integrate the system JComments on a form created with Fabrik, and this seemed to me the right way.

You can provide information to resolve this error?

Thank you
