BusinessObject :

I am trying to add an item to my list inside viewcontroller but I get this error:

I want to add some objects related to CurrentObject inside DetailView but it does not reflect. .

So I have managed to filter the data I wanted to get from SQL. But the problem is I can’t find a way to show this data inside Listview I am trying to create. It shows me all of the data instead of this particular data.

I have created a class (Business Object), which holds some properties for article information and a list of it’s own.
The basic idea is: I want to enter articles and save them into a list.
One of the properties is bound to a custom XAF Blazor editor.
I am starting to show the business object as DetailView.
With a button, I am adding the current information into the list property.
After that, I click on one of the list items, a new DetailView is opened.
When I now click on the custom editor, the dropdown get’s showed in the first DetailView (wrong position), where the custom control is, not in the new DetailView.
For better understanding, I have created a litte video: Video
