How does substitution work in OA Framework? What are the benefits of using Substitution in OA Framework?
Based on the user that has logged into OA Framework, MDS defines the context of the logged in user. Based upon this logged in context, all applicable personalization are applied by MDS. Given that substitutions are loaded as site level personalizations, MDS applies the substituted BC4J objects along with the personalizations. The above listed steps occur as soon as Root Application module has been loaded. The benefit of using Substitution is to extend the OA Framework without customization of the underlying code. This is of great help during Upgrades. Entity Objects and Validation Objects can be substituted. I think Root AM’s can’t be substituted given that substitution kicks off after Root AM gets loaded.
