If I go on a group, and I do any modification on it, then search, I can click Save multiple time in a row, it will always be accepted, and triger a new generation each time
However, if i return the group to its initial sate (after saving it with other parameters), it complains that it cannot be saved as there is no change.

The reason is likely that the comparision between the group parameters we wish to save and the reference is not valid, and we always check based on the group state we had when we displayed it the first time.
