setVersion(String) accessor breaks <version type="integer"> property access at runtime -------------------------------------------------------------------------------------- Key: HHH-1208 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1208 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.0.5 Environment: Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_05-b05) Windows 2000 SP4 Reporter: Adam Shackleford Priority: Minor I'm doing absolutely vanilla versioning, using an int version, and setVersion(int)/getVersion():int accessors. *But* one of my persistent classes had a setVersion(String) accessor (a NOP) that I left in for backwards compatibility with objects stored by XMLEncoder that I import with XMLDecoder. Having setVersion(String) stops XMLDecoder from complaining that it can't find the method. The method itself does nothing. THE PROBLEM: The presence of setVersion(String) confuses Hibernate when I save the persistent object. It ignores the setVersion(int) and tries to call setVersion(String), which yields a "BasicPropertyAccessor ERROR - IllegalArgumentException". Here are the essentials: ---------------------------------------- public abstract class Entity { private Long id; private int version; public Long getId() { return id; } public void setId(Long anId) { id = anId; } public int getVersion() { return version; } public void setVersion(int aVersion) { version = aVersion; } } public class Template extends Entity { public void setVersion(String aVersion) { // NOP } ... } <class name="Template" table="`TMPL`"> <id name="id" column="`TMPL_ID`"> <generator class="native"/> </id> <version name="version" column="`VER`"/> ... </class> BasicPropertyAccessor ERROR - IllegalArgumentException in class: mypackage.Template, setter method of property: version BasicPropertyAccessor ERROR - expected type: java.lang.String, actual value: java.lang.Integer AbstractFlushingEventListener ERROR - Could not synchronize database state with session org.hibernate.PropertyAccessException: IllegalArgumentException occurred while calling setter of mypackage.Template.version ----------------------------------------
