Unable to include context

I have recently updated from 1.4 to 1.6 and noticed some odd messages in the logfile. Here is part of my dialplan:

[deluxe]
include => default
include => music
include => conference-rooms
include => testing

[music]
exten => 280,1,NoOp(${CALLERID})
exten => 280,n,SetMusicOnHold(default)
exten => 280,n,MusicOnHold
exten => 280,n,Goto(s,2)

[conference-rooms]
exten => 1235,1,MeetMe(3339,Mip)
exten => 1235,n,Hangup()

[testing]
exten => 600,1,Playback(demo-echotest)
exten => 600,n,Echo
exten => 600,n,Playback(demo-echodone)
exten => 600,n,Hangup

I can access extension 280 and listen to MOH for as long as I like. I can enter the conference room as extension 1235 and the echo test on extension 600 runs fine from any phone. But when I load asterisk I see these messages on the screen and in the logfile:

[Apr 18 17:22:02] WARNING[2135] pbx_config.c: Unable to include context 'music' in context 'deluxe'
[Apr 18 17:22:02] WARNING[2135] pbx_config.c: Unable to include context 'testing' in context 'deluxe'
[Apr 18 17:22:02] WARNING[2135] pbx_config.c: Unable to include context 'conference-rooms' in context 'deluxe'

Are these of any consequence or is there something I should look at further?

since the functionality is there, the warnings are irrelevant. I think you have to have your “include” contexts defined before you reference them; therefore that’s why the functionality is added but with a warning.
