Hi,
I would like to implement something very similar to what is described in Question T2458. So I copied the code from the plunker,
but adding "isComposite" as custom property to the panel question is not working out for me.
In fact, it seems to me that these commands are not working:
Survey.Serializer.addProperty("question", "myPropertyName");
Survey.Serializer.removeProperty("question", "description");
Survey.Serializer.findProperty("question", "description").visible = false;
Thank you for your support!
