Bug: Version Control

Not using version control on your code is like playing Russian Roulette over the whole lifetime of your project.  You might not 'lose' anything at first, but later on you may regret the omission.

I had a strange bug upon opening the Ax Client related the to the inbuilt version control system, and didn't know where it came from

Translation: Error

A quick look in the logs, indicated the cause of the problem...

   Object Server 01:  
   [Microsoft][SQL Native Client][SQL Server]El nombre de columna 'MODIFIEDBY' no es válido. 
   INSERT INTO SYSVERSIONCONTROLMORPHXITE2541 (ITEMPATH,MODIFIEDBY,CREATEDBY,RECVERSION,RECID) OUTPUT INSERTED.CREATEDDATETIME VALUES (?,?,?,?,?) 

What fool did this then?...  Me!

For some reason we had added the ModifiedBy, ModifiedDatetime, etc, etc fields to the entity!  I may have done this accidentally when I added the fields to entities such as LedgerTable, TaxTable, TaxData...  Some of them had been added to the version control, and some of them were not.
