This directive is best used using the of method present in every directive. Calling A.of("role") will resolve to A.from(new Of("role")) which resolves to new From(A,new Of("role")). Usually this is followed by a call to from method, for example A.of("role").from(B). This will take results from B, change the active column and then feed them to A. Call to of must be before from to get the expected results. | This directive is best used using the of method present in every directive.
