Hi,  
I have two Custom properties in a popup window _ds1_ and _int1_: _ds1_ is of type `Dataset` and its value is passed to the popup window from outside when it is open; _int1_ gets its value from a field in _ds1_ through a `lookup` binding expression. Finally a **Dropdown list** `Selected value` property is bidirectionally bound to _int1_. When I open the popup my hope is to have the _Dropdown_ show the value in the database. On the contrary it seems the binding is not working at all (which is not the case, because if I then change the dropdown selected item, _int1_ gets the new selected value as expected).

Any suggestion?

Ignition version: 7.9.9 (b2018081621)

**UPDATE**  
I realized that the described behaviour was due to a script I execute when the Root container `componnetRunning` property turns `true`. It’s all working as expected, sorry about that!
