Subject Re: Testing Stratos 4.1 - application removal still fails in certain cases
Date Thu, 25 Jun 2015 11:49:22 GMT
Hi Martin,

Do we know whether this error is correct in this scenario?

org.apache.stratos.rest.endpoint.exception.RestAPIException: Cannot remove
cartridge group: [group-name] sub-G1-G2-G3-1 since it is used in another
cartridge group or an application

BTW it would be better if we can list the groups/applications which are
referring this cartridge group in the error message.

Thanks
