Add a conversation to an express entity

Permalink
Hi.
I have a bunch of express entities and I would like to add the possibility for my users to add comments on each entity. Since each entity page is generated from a form I don't have a page to attach it to.

I have come up with to possible solutions but I don't know how to solve either of them. I'm hoping for your help on this... :)

1. The obvious one to have a conversation linked to the entity ID. But is that possible?

2. Add an entity object with a one-to-many association to build my own conversation. But then I have issues with the associations. I don't want my users to have to choose which entity it belongs to. I need to auto-select the owner and hide the dropdown-box in the form. I've tried to add a hidden input field to the output of the form rendering but I can't figure out how to set up the input attributes to make it work.

Any input is appreciated, I'm new at Concrete so perhaps I'm missing something obvious.

Thanks
Mats
