Graph Validator + Tomcat 8.0.8: interpret empty strings as null is ignored -------------------------------------------------------------------------- Key: RF-13648 URL: https://issues.jboss.org/browse/RF-13648 Project: RichFaces Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 4.3.7 Environment: Tomcat 8.0.8, OpenJDK 7, OpenSuse 13.1 x64 Reporter: Tony Cramer Assignee: Juraj Húska Attachments: rf-demo.zip {{javax.faces.INTERPRET_EMPTY_STRING_SUBMITTED_VALUES_AS_NULL}} is ignored during Graph validating. Some debugging info: Object being validated ({{value}} argument) in method {{org.richfaces.validator.BeanValidatorServiceImpl.validateObject}} contains empty strings (""). Expected behavior: There should be nulls in properties, because interpreting empty strings as null is enabled. This causes validation to not pass. Something has changed in _jasper-el_ in Tomcat 8.0.8 which I updated recently from 8.0.5. If I replace _jasper-el.jar_ from Tomcat 8.0.5, everything works. Tomcat bug or RF bug? Edit: It's definitely JSF/RF's issue. Tomcat EL has changed to meet EL spec. https://issues.apache.org/bugzilla/show_bug.cgi?id=56522 Edit: Simple project for reproducing the issue attached (rf-demo.zip). - Build WAR with Maven (3.2.1 tested) - Get a clean Tomcat 8.0.8, unpack - Place WAR into webapps - Run tomcat - Open http://localhost:8080/rf-demo-1.0-SNAPSHOT
