Adding Comments as a Related List

[acmfox]

Thanks for this module, it is awesome. I have had success adding related lists for modules like Accounts and Documents, but I cannot add the Comments module as a related list.

I go through the process and all seems to work, however, the Comments relationship is not saved. When I reload my module in the designer, the other items I put in the related lists tab will be present but the Comments relationship will be missing.
