wpa_cli -a is calling the action script only for connect, not for disconnect

Which version of wpa_supplicant are you using?

There is supposed to be disconnect message and this works in my test.
When I'm using wpa_cli to connect and disconnect while running wpa_cli
-a in the background, I see following output in the action script:

$ ./wpa_cli -a $PWD/action.sh -p Ctrl
Selected interface 'sta0'
ACTION: sta0 CONNECTED
ACTION: sta0 DISCONNECTED
ACTION: sta0 CONNECTED
ACTION: sta0 DISCONNECTED
ACTION: sta0 CONNECTED
ACTION: sta0 DISCONNECTED


The disconnect event generation shows up in wpa_supplicant debug log:

RX ctrl_iface - hexdump_ascii(len=10):
     44 49 53 43 4f 4e 4e 45 43 54                     DISCONNECT      
wpa_driver_test_disassociate addr=02:b8:a6:62:08:5a reason_code=3
Setting scan request: 0 sec 100000 usec
Added BSSID 02:b8:a6:62:08:5a into blacklist
CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys

(that last line is sent to wpa_cli, too)
