Content part editing view not displayed when creating a content item in Orchard

Question

I created a content part and then added it to a content type in Orchard. But when I try to create a content item of that type, the fields for the part's properties are not displayed. I'm looking for suggestions of where the problem might be.

UPD: the relevant code:

You're probably missing an entry in placement.info.

Add this into the placement.info file in your module (not the placement.info for yoru theme, since the theme is not active while you're in the dashboard):

`<Place Parts_Ad_Edit="Content:1" />`
