How to post the value in wevix from pop to parnet window

Hello,

I have a webix page where I am displaying a form with multiple fields, and one button which will open the window using (view : “window”) this window having a data table, not this looks a parent and child window, my requirement is I need to open this window and once I will select the one the row, I need to post the value in one text box field in parent, I am able to get the selected value, but when I am doing $$(“quoteName”).setValue(“value needs to post”); I am getting the below error.

SCRIPT5007: Unable to get property ‘setValue’ of undefined or null reference

I wanted to know whether this could be possible or not,I am using the angular controller and all the code is in one controller only.

If you are using iframe, so two real pages are involved, you can use

parent.webix.$$("quoteName").setValue(some);
