Append new item to group. Group does not update

I just appended one item to two different allready existing groups. The item does not show in the sitemap groups Is this a correct behavior? After a reboot it is working as it should. What do I have to do to become the groups updated on a running system, without making a reboot?

I have not found an issue raised against smarthome
