Hi Shaheed, Yes currently it is not possible to define a cartridge group inline in an application definition. We first need to define the cartridge group in global level and then refer it in the application.
We could introduce a new feature to support this in a later release. Thanks On Wed, Mar 18, 2015 at 3:51 PM, Shaheedur Haque (shahhaqu) < [email protected]> wrote: > OK, thanks for the explanation.
