> NPE was thrown while running the datadump task on MSSQL database. It first happened on Torque-gen 3.1 which has village-2.0.jar, so I took the village-3.3.jar from torque-gen-3.3.
> I did a search and found this link http://mail-archives.apache.org/mod_mbox/turbine-user/200401.mbox/%3C373EC11E4993DF4F9DCBD2E630568CE31F82F9@xch-au-20.au.nos.boeing.com%3E
> Looks like someone found that out in 2004.
> For village 3.3 the NPE is in Value.java line 153. I checked out the village source from svn, put a null check and I was able to get my datadump working. It's a simple null check fix. I don't see where to attach a file to this ticket so i'll just post the code here.
