Problem

 When trying to change a project property, user gets error -11149, Cannot save instance to storage (instance id ...,class id....,class name...)

Solution

The problem was with id columns in the database that were set as a numeric data type and should have been int.  problem occured after incorrectly converting database from Oracle to SQL

PROJECTTYPEID needs to be an int NOT a numeric data type
UNIQID needs to be an int NOT a numeric

example query to fix a particular table:
alter table I_CTDOT_BRIDGE_BEN alter column PROJECTTYPEID int;

user should always backup database before altering the database
