I have enabled Custom Form module and now I can see in parts list new part named Custom Form. Then I've created my own module and there are to my own fields. With migrations I added this fields to orchard project.
Now I'm trying to add this fields to my custom form part and besides I'm adding another to fields, which are in Orchard library (for example Boolean Field and Date Time Field).
Then I go to Forms in left panel and Add New Custom Form. I allow to show it on menu. When I go to this form in front-end I can see Boolean and Date Time Fields, but can't see my own fields.
But if I create a new Content Type and add Custom Form part to this type and then create new item of this content type I can see in front-end 4 fields: Boolean and Date Time fields and my own fields.
It's interesting enough, why it's happening? May be I'm doing something wrong?
But I think it's probably a bug...
