I read that when setting attributes using <c:set var ="attributeName" value = "attributeValue"> it deletes the attribute if the value is NULL.
My question is if i donot give a scope it first looks in the page Scope. Assume the attributeValue is NULL. It deletes the attribute from the Page Scope
What about other scopes. What will it do if there are attributes with same name in other scopes like request, session and application?
Will they be deleted too??
