[Freeswitch-users] sched_api doesn't get launched

Thanks to c6burns on IRC channel for the tip to use execute_on_answer in
combination with eval, and of course everyone here that pointing me to the
right direction.
I was able to execute sched_api with eval, but not with the combination of
execute_on_answer. The argument just don't get parsed as the eval argument.
Here is the code:

setVariable("execute_on_answer", "eval sched_api(+%ld none uuid_displace
<some uuid> start
/usr/local/freeswitch/sounds/en/us/callie/misc/8000/final.wav 20 mux)");


Here is the log:
2009-10-23 16:17:53.633189 [DEBUG] switch_scheduler.c:214 Added task 2
sched_api_function (none) to run at 1256285888
EXECUTE sofia/internal/1688004 at 192.168.1.66 *eval(+OK *Added: 2
)

2009-10-23 16:18:04.52701 [DEBUG] switch_channel.c:1927 sofia/internal/
1688004 at 192.168.1.66 *execute on answer: eval(sched_api(+37 none
uuid_displace 84d74f41-8668-4138-943f-f076e94046ad start
/usr/local/freeswitch/sounds/en/us/callie/misc/8000/final.wav 20 mux))*
EXECUTE sofia/internal/1688004 at 192.168.1.66 eval(sched_api(+37 none
uuid_displace 84d74f41-8668-4138-943f-f076e94046ad start
/usr/local/freeswitch/sounds/en/us/callie/misc/8000/final.wav 20 mux))


The first part of the log is when I just do execute("eval",
"${sched_api(+%ld none uuid_displace <some uuid> start
/usr/local/freeswitch/sounds/en/us/callie/misc/8000/final.wav 20 mux)}");
And I simple get a OK, and then later on the sched_api gets executed.

However, on the excerpt of the second log. which I use the combination with
execute_on_answer like specified in the yellow hight code above. It doesn't
simply return a OK, instead it shows the whole blob of code. and does
nothing later.
