RHQ displays resource list as a result of operation for grouped resources and then the user has to choose one of them to see the actual result for each resource. It would be nice if the results of operation for grouped resources were displayed in the same place so that the user can see these all results at the same time. Operation results are stored in an RHQ Configuration object, and we already have a GUI component that can display a side by side view of multiple RHQ Configurations, which we could leverage. However, there would be some additional work to indicate the lack of results for any members of the group whose operations have either not yet completed or failed. Also, I don't think it would be practical to display side-by-side results for a operation invoked on a group with 300 members or for an operation that returns a results containing a list of maps; for such cases, we could probably just disable the aggregate results and display a note to the user explaining why.
