I created a custom Promotion type using the new Promotion system.
Later, I deleted a property from my custom class...
But in the UI that property still appears! I guess there is some old data hanging around in the database? Have you ever experienced this? What is the best way to solve this?
(I can provide a screenshot if necessary)
I usually go to CMS -> Admin -> Content Type -> Marketing -> [The discount in question] -> [Property in question] and remove it from there. You'll see in the farmost right column in the property table if they exist in code or not. If they don't, you have the option to delete it once you click into the property.
This will delete the property from the marketing UI and also delete its stored value in the database in tblContentProperty.
Nice, that worked. Thanks Joel!
