Bridge-group 1 in a WLAN environment

Question

I'm configuring some AP 1130 AG.
For customer requirements I cannot use the VLAN 1 but in particular a VLAN 102 for the management and the VLAN 117 for the WiFi users. At this point I configured the switch port in trunk with the vlan 117 and 102 as native. In the AP I configured a fast ethernet interface0,vlan- id with the vlan-id ugual to the native vlan (102) I wrote also encapsulation dot1q 102 native. As bridge-group I tried to leave the bridge-group 1 but I lost the connection. If I put as bridge-group 102 all is ok. Why? I know that It is not necessary to specify the bridge group to which the FastEthernet interface 0.native_vlan_number belongs. It will be associated by default to the bridge group 1 used for the administration of the access point. I don't understand why? is there a link between bridge group 1 and vlan 1 (that I put down in the switch)?
