How to Set Boolean attribute to null
I am implement nested Boolean condition (yes/No), and I don't want default value to set either true or false
so Let say attribute
when A changes to = No ; only at that time I take Boolean value for attribute for B.
My question is how to set Boolean attribute to null or clear it.
Because in my case the processes in loop, even I don't set value for attribute B, is still sets to false.
I must clear this if A attribute is yes
