0007915: Objects are not set to the group, when they are rezzed or created
Hello !

I have found problem: that objects are not set to the avatar's group,

when they are rezzed or created in 0.9.0 versions.

Other residents also confirm this issue.

I have found and isolated reason of this situation.

Problem exists in GroupsModule.cs file.

When avatar logs in the region then, everything in problematic thing, work as

it should.

But when this avatar teleports itself to region running on 0.9.0 version

then OnMakeRoot does not update avatar's group at all !

And in this way, all created and rezzed objects are not set to the avatar's

group at all.

That is really serious major issue that requires fixing.

Objects should always inherit avatar's group, that is one of assumption

of security and management prims in the region.
I have found comment in a file:

" // we should send a DataUpdate here for compatibility,
            // but this is a bad place and a bad thread to do it
            // also current viewers do ignore it and ask later on a much nicer thread "

Well I agree that maybe it should be done in other way, but withotu this

DataUpdate, objects are not set to the group.

I have added line:


and compiled simulator and tested it, It works now.

But i do not publish patch, because i think it can be done better.

Let developers express their opinions.

 I added this line to file:


to make test in OSGrid, that works with XMLRPC Groups

No tags attached.

Again me :)

I have been told about certain examplificaiton of situation, where this updating

makes really serious difference.

Dan Banner has announced me about so called "door problem":

When we use object = door with script that includes: llDetectedGroup function

then in actual os 0.9.0, when we rezz new door,

script does not recognise our group, to make it work:

we need to re-wear our group's tag, to force simulator update data.

So it only shows, that fixing this UpdateData in onMakeRoot,

is really necessary.

With my line:


it cures problems, but because developers claim in the code,

that it should be done better, we need to wait for an official statement.

I restored the SendAgentGroupUpdate to master. Fixed?
2016-06-11 13:46   
tested and works as expected :) Thanks

I thought that osgrid was using the old groups module, no?

Ahh, this is still an issue when a group invite is sent. Searching and joining a group seems to work fine and rezzing in active group seems good.

OSGrid groups work in this way:


Enabled = true

Module = GroupsModule <-- This module can use a PHP XmlRpc server from the Flotsam project

ServicesConnectorModule = XmlRpcGroupsServicesConnector

GroupsServerURI = "" [^]


It is absolutely enough ( for regions located in OSGRID ) to modify

this file: \OpenSim\Region\OptionalModules\Avatar\XmlRpcGroups\GroupsModule.cs

not this: /OpenSim/Addons/Groups/GroupsModule.cs !

can you precisely and logically explain changings in /OpenSim/Addons/Groups/GroupsModule.cs ?

Problem that has been introduced in this mantis is related to OnMakeRoot only !!

not for OnNewClient !!!

Version: OpenSim Dev OSgrid (Dev) e0a82a8: 2016-06-14 (SIMULATION/0.3 - SIMULATION/0.6)

Still rezzed objects are not set to the group that avatar has activated.

And i want to explain once again:

Problem is not when you log in and rezz,

but problem is when you teleport avatar and then rezz !

Simply saying: Problem exists in OnMakeRoot and not in OnNewClient !

And it must be also remembered that OSGrid uses: XmlRpcGroups !!

I have attached the patch.

Robert Adams restored it but not in proper place in my opinion.

There was not any problem with setting group on rezzed objects, when avatar

just logged in.

Problem only concerned and concerns situation:

avatar teleports itself to other region and then rezzes or creates object.

SendAgentGroupUpdate does not work after teleportation.

Please verify my patch, compile and test it.

Mandarinka: I didn't use your patch, because I wanted to bring MisterBlue's comment too.

No problem Diva :) The important is to make it work correctly.
2016-06-20 10:23   
I believe this has been fixed, yes?
Mandarinka Tasty   
2016-06-20 11:19   
Yes, I confirm it works in both situations:

OnNewClient = avatar logs in and rezzes object


OnMakeRoot = avatar teleports itself to next region and rezzes object

Rezzed / Created objects properly inherit avatar's activated group =

correctly set to this group.

I have verified it against last OSGrid release:
