Mandar Ambawane commented on ATLAS-3872:
----------------------------------------
*Cause of the problem:*
Type-def Column is created by quick-start script.
Here in this case, Type-def Column has the attribute "name". And it has
property isOptional = true
Type-def Column is a child of Type-def Asset which also has the attribute
"name". And it has property isOptional = false
Now while creating Entity of Type-def Column from UI, it does not show
attribute "name" in the mandatory fields because for Type-def Column its
property isOptional = true
But while validating the attributes from server side we iterate through all the
attributes of Entity type (Including Parent's attributes)
In this case, while validating Type-def Asset's attribute "name" (which has
property isOptional = false) we get an error because its value is sent as
"null" from UI side.
