Asterisk DB and "Away" status

[Ross McKillop <rm@xxxxxxxxx>]

I'm having issues with implementing an "Away" status to be shown on  
FOP..

Examples of my extensions.conf and op_astdb.cfg are below

When starting asterisk and fop the button appears semi-transparent  
(but with a green status LED and no away text)

If I then dial 50 to take the away status "off" the button returns to  
it's normal opaque state, if I then dial 51 it works as expected,  
marks the button as "Away" and changes the LED colour and the  
background to be semi-transparent again.

However, if i then dial 50 again to return to not being away, after  
around 10-15 seconds the button returns to it's transparent state (but  
the LED colour and text do not change)

Any ideas what could be causing this ?  (I've had a look with debug  
set to 7 and I can see the events where it changes the colour of the  
led icon, the text and the transparency for both dialling 50 and 51  
but there's no similar events being shown when it reverts back by  
itself to the semi-transparent state).

Any advice offered would be gratefully received (p.s. am running  
version 0.27)
