i want fetch db requirements related given project(in case currentproject) i've used 2 ways this first 1 : requirement.withcriteria {.... eq("project", currentproject) ... } i note query doesn't use equals method of project class, query returns me want. second requirement.withcriteria { .... currentproject == property('project') ... } this query use equals method compare 2 projects, not overwrite equals method exception has been thrown saying "grails can't cast hibernatebuild domain" so, wonder know difference between 2 queries ? thanks all! withcriteria method goes database fetch entities. on database level there no concept of equals (db not know java). first query gives right results because compares db mapping (primary / foreign keys). as second query - not advice use it. if uses equals, when fetches projects db memory. , bad idea.
