Bug when creating a listview programmatically, the binding of the first Element will always fail

I'm using the official bind-to-list example, and try to create the game_switch.uxml programmatically

The binding of the Toggle fails, and binding of TextField succeeds. it looks like

Then I moved the toggle code after the textfield code
var box = new Box();
box.style.flexDirection = FlexDirection.Row;
var tf = new TextField();
tf.style.flexGrow = 1;
tf.bindingPath = "name";
box.Add(tf);

var toggle = new Toggle();
toggle.bindingPath = "enabled";
box.Add(toggle);
return box;

This time, the binding of TextField fails and Toggle succeeds.

 

I'm nowhere near familiar enough with this (poorly-documented-mess) yet to be of help, but are there any console errors/warnings being logged?

 

No. No errors/warnings. It's just a bug. Easily reproduced
