So i've created a custom component and name it to CustomDropDown then add a DropDown control:

tif_st_0-1657798093541.png

then I create an Input custom property with name Items:

tif_st_1-1657798241310.png

then I set my DropDown1 Items property to: Parent.Items

tif_st_2-1657798286731.png

then I create an Output property with name Value:

tif_st_3-1657798355122.png

then I set my Value property to: Dropdown1.Selected.Value

tif_st_4-1657798475754.png

then on my Screen1 I insert CustomDropDown_1:

tif_st_5-1657798752788.png

then on my Screen2 I insert CustomDropDown_2:

tif_st_6-1657798830205.png

then I put Items of CustomDropDown_2 to [CustomDropDown_1.Value] but I get an error :

This rule create a circular reference properties.

 

Is it an intended behavior? because if I try to put CustomDropDown_2 in same screen with CustomDropDown_1 it doesn't show that error. If it is not, what did I miss here?
