Hi,

Using the VisualBuilder, I am creating a DynamicForm (Order) for which I want to display related records (OrderItems) in a ListGrid below the form.
Both (ListGrid and DynamicForm) are members of a VLayout (I tried both orders, ListGrid above DynamicForm and vice versa).
There is a foreign key for Order in OrderItems (like in the built-in example datasource).
Now, I cannot make the Order DynamicForm to trigger loading related OrderItems in the ListGrid below. I tried adding a FetchRelatedData Action to the itemChange event of the DynamicForm (I also tried other events and events on DynamicFormItems directly), but the VisualBuilder just tells me
Code:
Visual Builder couldn't find an automatic binding from event itemChange to action Fetch Related Data
I believe this should be possible somehow, right? But how?
Please advise if you need further information/demonstration.

Thanks,
