Currently in the attribute form, if more widgets points to the same field, when one of them change value all the duplicates are updated in
onAttributeChanged
. During update they send the same valueChanged signal andonAttributeChanged
is called again and again with the same value and field that was already handled.This P.R. will block duplicate widgets from sending
valueChanged
signal in this context.This fixes #50859
