Persistence problems with Object relational mappings ---------------------------------------------------- Key: HHH-2375 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2375 Project: Hibernate3 Type: Bug Components: core Versions: 3.1.2 Environment: HSQLDB, MyEclipse 5.0, JSF , Spring Reporter: bansi Priority: Blocker My web application uses JSF 1.1.01 as Presentation Layer Spring 1.2.6 as Business Layer Hibernate 3.12 as Persistence Layer The JSF form has - One drop down which automatically populates the remaining textfields on the form -One h:selectManyListbox which populates all the possible user Roles - Add /Remove h:commandButtons - One h:selectManyListbox which gets populated with selected user roles on click of Add button. This will work only if i set the scope to session in faces-config.xml I have two POJOS i.e. DeviceType and Role. The relationship is uni-directional and Many-To-Many. That means DeviceType can have multiple Roles. Expected Results : If i persist DeviceType object then i expect the following insert statements to happen 1)insert into DeviceType(Id, Name, Desc) values(?,?,?) 2)insert into DeviceType_Roles(DeviceType_Id,Role_Id) values(?,?) Please Note DeviceType object is associated with set of Roles Observed Results : 2007-01-21 20:53:26,796 ERROR [org.hibernate.property.BasicPropertyAccessor] - <IllegalArgumentException in class: test.Role, getter method of property: id> 2007-01-21 20:53:26,796 WARN [test.TestBean] - <IllegalArgumentException occurred calling getter of test.Role.id; nested exception is org.hibernate.PropertyAccessException: IllegalArgumentException occurred calling getter of test.Role.id> Here is my posting on Hibernate Forums : http://forum.hibernate.org/viewtopic...981&highlight= Please Note I have read the Hibernate Documentation extensively & strictly followed the example . Nothing helps hence looks like its a Bug with Hibernate 3.1.2. Please note i am using hibernate 3.1.jar and hibernate-annotations.jar under Spring 1.2 ORM/DAO/Hibernate framework -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
