Hey, no I haven’t found a solution yet.
The problem is, that you can’t set a new session Item, after opening the lightbox:
This works:
session.setItem("key", "I am a String");
wixWindow.openLightbox("Formular");
This doesn’t work:
wixWindow.openLightbox("Formular");
session.setItem("key", "I am a String");
You can try it with a container instead of a lightbox.
