Now that Simulation jobs write
xAOD::EventInfo rather than legacy
EventInfo in master. It is possible to set the
xAOD::EventInfo error state in a less hacky way that was used for
EventInfo. Follows on from !50332 (merged).
In future it would be nice to be able to set the error state in the ISF SimKernel(MT) algorithm also, but that needs a bit more thought about how to propagate the condition from the individual simulators.
