I am trying to add a custom action to a GridField row using the following SilverStripe documentation:
I am getting the error:
Uncaught Error: Class "SilverStripe\Forms\GridField\AbstractGridFieldComponent" not found
The class does not seem to exist in 4.10.8 but I can see it in 4.11 which I don’t think has been released yet. Is there any documentation available relevant to 4.10? Or does someone have a module I could look at that shows a good example of this implementation?
