Hi, I am trying to persist a view and get this error message:

{"code":7, "message":"feature not supported: \"GE***$TEC\".\"$$VIEW_MATERIALIZATION_ON$$\": line 378 col 7 (at pos 13641): cannot support create association to a temporary or virtual table", "insertingData":false}

In this view there are 4 associations. One of them seems to cause the problem. When I delete it I can persist the view. The association is using another view from another space. The strange thing: I could replicate that associated view. That doesn't make a difference.
