Hello
I'm working on a Joomla module and willing to integrate the "Add as a friend" button and the Message Button.
First one was not a problem, but when it comes to the Message button , the popup opens and an error message shows:

Sorry, but the list id provided is not valid.

In the documentation here: http://docs.stackideas.com/developers/html/conversations
it is stated the data-es-conversations-listid is not required.

So what am I doing wrong or missing ?

Just to say. I'm willing to message only one user. The error mesage shows even if the user to be messaged is s friend.

Thank you for your help

Adrien
