Hi,



I changed multiple tables (removed 60% of columns) and remapped them. I then restored the database and got my columns back. I remapped the tables against the restored database however most of our columns are mapped as 'use nullable generic' so I thought I would make the change directly in the dbo.DTEproject_item_exceptions table however the columns I deleted are no longer in that table.



I take it that dbo.DTEproject_item_exceptions only contains columns that have been customised and remapping the BO didn't recreate them because they haven't been customised yet. Is there any way, other than using the bo mapper manually, to add my missing columns to dbo.DTEproject_item_exceptions table and set them all to 'use nullable generic'?



Cheers, Peter

Hi Trent,



Yes, we get the following error after clicking the Wizard and while 'populating tree view' is displayed. Given that no other users have reported this issue we presumed it had something to do with a project in our environment. When this first occured we had mapped 95% of all our BO's and we simply managed all the rest without the Wizard. If we could somehow map all our columns to "use nullable generic" that would be a great help.



At the moment I'm trying to nut out what project is causing the exception.



Cheers, Peter

It looks like this is happening when it is attempting to fill the projects. Have you been manually updating the StrataFrame DTE tables? There could be stray record or two if this is the case. Also, if you do this for a new project, to confirm, it doesn't fail. Correct?
