no_sensor() only works with sensor(integer number)

I have an object with a script that essential cleans things up that are rezzed by the same object. It runs llSensorRepeat() once a minute to see if AGENT is near, and if not, it issues commands to clean up the rezzed objects.

It works as it should, but =only= when I have event:

sensor(integer number)
{
}

in the script. I do not need to know if AGENT is near, only when AGENT is =not= near! But, if I remove the sensor(integer number) event, the no_sensor() event does not trigger!

I look in jira and do not find report of such a bug, maybe it is? Nothing in wiki says it is required.

Of course, the work around is to include the sensor(integer number) event, even though it does nothing.

Has anyone else experienced this?

Note: Using the no_sensor event without a sensor event will cause the repeating sensor to stop. Use a "dummy" sensor event with nothing inside the brackets if you just want to react to something not being found.

Thanks! I was using the LSL Wiki in world from the Script -> Help menu and it did not mention that little note at all!

I know, drove me crazy until I found it, the in world and official wiki are far from complete or accurate.
