Autostart with AutostartCondition

I want to run some program at the certain condition.

So I have created .desktop file and put it int /etc/xdg/autostart.

Here desktop file is:

[Desktop Entry]
Type=Application
Name=System Tray
Exec=/opt/testApp
OnlyShowIn=GNOME;Unity;
NoDisplay=true
AutostartCondition=GSettings com.test testVal
X-GNOME-AutoRestart=true

And I have made a custom key with gsettings for a condition and compiled the schemas.

I confirm if the schema works, it works.

$> gsettings set com.test testVal true
$> gsettings get com.test testVal

I typed the command above, and got "true".

However the Application I registered as Autostart doesn't run.

Do I have to restart or logoff for a test?

Is there a way to test autostart without reboot or logoff?
