When naming K2 artifacts, such as processes, roles, reports, SmartObject system names and custom user managers, certain characters are not allowed. These special characters may be in use by the K2 server, by the underlying technology platform, or are simply not allowed because they may cause unforeseen problems.
SmartObject system names can only include the underscore ("_") character. Characters for SmartObject display names, including the name of the SmartObject and property, parameter and method names, are limited by the designer.
