llGetLandOwnerAt() bugs?

I am making a simple land scanner that will tell me who owns land within a SIM.
I am useing llGetLandOwnerAt() but I have found that it will only give me the name of an owner if they have been inside the SIM while I am online.

Is this a bug or some wierd feature?

is there any other way of getting a list of who owns land inside a SIM?

llKey2Name() only works when the av or object is in the sim at the time. You can fetch the name through a slower method: llRequestAgentData().
Note that if the land is group owned, getting the name is (I think) impossible.

ok, thank you very much.

(updated)_
I just tried it and have found no matter what I get keys instead of the name
what has this warped brain looked over again?

As Jillian mentioned, use llKey2Name() to translate the owner's key to something more readable.

llKey2Name doe snot do what I need it to do all the time.
However Jillian's sugestion of useing llRequestAgentData() worked after I fixed some umm

crap in my code.

But thanks all for the help.

Are you getting keys returned in your dataserver event?

Can you post your code? There's a rare bug where a script will expect a name, but get a key instead, but I'm not sure that's what's happening here. The dataserver can be tricky.
