Found couple of issues with n-level-nesting, fixed those and pushed to master. Created a sample with 5 level nesting and everything works fine.
Please refer the n-level-nesting sample application https://github.com/apache/stratos/tree/master/samples/applications/n-level-nesting for more information.. Thanks.
