Since your development environment is working, I would suggest changing your development model's connection dictionary so that it is connecting to the deployment database. Then you can test to see if the problem is with the database.
You may also want to reverse this concept and point your deployment app to your development database. See if this still creates the problem.
By pinpointing what changes and environment are causing the problem, I'm sure you'll be able to find the cause.
Are you able to Browse Data through EOModeler on the changed table? Does the length of the new column match the length of the table column? Does it have the correct Value Type?
Keep hunting... I'm sure you'll find the answer. And it will probably seem so obvious once it is found.

Greetings:
About a week ago, I sent an email to the list about a completely useless exception I have been getting:
Application:
MyApp
Error:
java.lang.NullPointerException
Reason:
Stack trace:
File
Line#
Method
Package
NA : Non applicable, JIT activated
This gives me virtually no information, and I have no idea what to do about it. I am running WO 5.2 on Mac OS X Client for deployment. Openbase is the back-end database. I am developing the site on a different Mac OS X Client machine. This exception only occurs on the deployment machine, and only when I go to one particular database driven component. This component has not been recently changed, and was working fine before a week or so ago (I did other minor changes to other parts of the site, and those parts work).
The database is pretty simple, and has only about 5 tables represented by EOs. I did add a column to one of the tables in the EOModel, and I reflected this on the deployment machine by adding a column directly on the database, and filling it in appropriately. (The development tools are not on the deployment machine) This new column affects one of the other components, which works (in addition to the one that doesn't.
I have checked the various logs and the console when the exception occurs, and there doesn't seem to be anything to explain the problem.
Basically, the site is now useless, and I am being left with the possibility of again having to consider other application platforms, because I can't get this to work, or a complete reinstall of the OS, the database, WebObjects, etc.
Any help would be appreciated. _______________________________________________
