I have created some groups for each sites we have.
I would like to add the last 25 events to the Group Details page and have it filtered to display all the events for all the nodes in that group.
When I add the last 25 events to the page I can create an SQL filter but cannot see a node property (for which group it is in).
Does anyone know what the SQL for groups would be or even if this can be done without using a custom property?
