We recently converted our project from 6.10.3 to 7.5.1 and our custom login flow has stopped working.
After much investigation we have found in the release notes : https://docs.mendix.com/releasenotes/desktop-modeler/known-issues and https://docs.mendix.com/refguide/moving-from-6-to-7 that the stateless runtime does not transfer the seesion when using a custom login java action.
We need to use the custom login, as users are only allowed to login after being authenticated against our IBMI server using a rest service.
Does anyone know a workaround?
