[Opensim-users] Caught exception when detaching object (OS 0.7.1 Dev)

Mon Feb 28 01:14:27 UTC 2011

If you look at the stack trace you'll see that both contain the text

at OpenSim.Data.MySQL.MySQLGenericTableHandler`1.Store(T row) in
c:\Documents and Settings\Chris\Desktop\opensim-tree-6bd18eb 0.7.1 Dev\OpenSim\
Data\MySQL\MySQLGenericTableHandler.cs:line 224

which suggests that they are both the same error.  This line is probably failing when it finds null in a public 
XInventoryItem field and promptly tries to dereference it.  That particular situation needs to be handled better.

I think this is a bug and does need to be fixed so please raise a mantis and reply to this thread to tell us what the 
number is.
