GValidation is a validation plugin for Griffon - A Grails like application framework for developing desktop applications in Groovy. Like most part of the Griffon framework GValidation's syntax and usage closely resemble its cousin Grails' validation and constraints support. However the similarity pretty much stops here, since Griffon model are very different from Grails' concept of model. In Grails model usually refers to domain classes that are bound to database, however in Griffon models are usually just mere POGOs thus this plugin is designed to work with Griffon models as well as any POGOs.
GValidation is written mainly in Groovy while retaining most of the syntax of Grails constraints support. For more information please checkout our wiki page
