llResetLandBanList() and llResetLandPassList()

I'm not sure if this is a jOpenSim issue but asking just in case - I have found the although I can use the scripting functions to add or remove a user from the ban list or pass list (llAddToLandBanList etc) if I use the functions llResetLandBanList() and/or llResetLandPassList(), if there is at least one user on the list, I get an exception error thrown (it does remove the first person on the list but not others)

There seems to be a problem in your script. You should check your lsl script.
The add/remove/reset ban/pass list functions work well on OpenSimulator.
This problem is not related to jOpenSim.

Sorry but with even a simple test script I also found it gives an error on a parcel on Canary island. The script is:
//
default
{
touch_start(integer num)
{
llResetLandBanList();
}
}
//

The error is:

Just a follow up that I managed to get this on when using an OSGrid avatar on a sim that I'm pretty sure has no links with jOpenSim stuff and is running 0.9.1, so I'm guessing this is a general OpenSim issue so will post there.

I'm intrigued you seem to be able to get it to work though?

(Note: It works fine if no names on the ban list but if there is one, it throws the error but still removes the name.)

Sorted in the latest build now
opensimulator.org/mantis/view.php?id=8563

As djphil mentioned, this is not jOpenSim related.

And do you really think I give permission for llResetLandBanList() on the free parcels on Canary Islands?

Yes I understand it isn't jOpenSim related but initially I did think it may be as it is to do with profiles in a way and also I couldn't believe (much as djphil also did) that this would be a general openSim error.

However, yes , it turns out people can't use those script functions much as it was an error in opensim that now has a fix built into the latest 0.9.1 build.

PS as it's an lsl script thing, it should work fine in any parcel that the scripter is owner of, so not sure I understand your last point? My reason for trying it there was I was checking if it was local to my grid before posting in opensim mantis (I also tried on a third grid and all gave same response, so was easy to document steps to get the bug.)

Hello,

as you may have noticed, the bug was found on XEngine and YEngine and is now fixed (see Mantis 8563 ).

I have little time right now so I could not test it fully but it should work better now.
If you find that the problem has been solved then it is good to close the mantis indicating that it is solved.

Thanks to you for reporting this bug
