|Overview of Validator Column configuration screen|
Pattern Comparison allows the Bamboo Validator Column to compare a value entered by a user with either a pre-defined pattern or a custom expression of your own. In addition, you can use and/or logic to require that an entered value matches multiple patterns, or one of several possibilities.
