I'm creating a simple blog with categories using the DataObjectAsPage Module.
I have a DataObject called BlogCategories that has a belongs_many_many relationship with the BlogPost DataObject.
Everything works fine, apart from when you are editing a BlogPost and adding categories - the 'Link Existing' dropdown shows Category IDs rather than titles.
I'll try and add a screengrab below so you see what I mean...
I'm not manually adding the GridField (as per this tutorial), this is simply how SilverStripe is doing it by default. I have also tried adding the GridField manually, but that does the same thing.
Can anyone point me in the right direction?
