Are embedded property references possible in the expression language? For instance, something like

```auto
!isNull({../Dropdown_{this.custom.dropdown}.props.value})

```

Where the goal is to evaluate `{this.custom.dropdown}` first (ex. dropdown = 'Type') and use it within the `{../Dropdown_Type.props.value}` reference.

No.

But you can use the `property()` function.

Thanks.

```auto
!isNull({../Dropdown_{this.custom.dropdown}.props.value})

```

becomes

```auto
!isNull(property("../Dropdown_"+{this.custom.dropdown}+".props.value"))

```
