spring - Hibernate, properties changes not tracked -

i'am writting web application spring webflow 2.4 , hibernate 4.3. have problem changes made on entities after calling persist(). changes not tracked , calling saveorupdate before end of flow doesn't (and should useless anyway).

hib config

<bean id="oracledatasource" class="org.springframework.jdbc.datasource.drivermanagerdatasource">         <property name="driverclassname" value="oracle.jdbc.driver.oracledriver" />         <property name="url" value="${db.oracle.url}" />         <property name="username" value="${db.oracle.user}" />         <property name="password" value="${db.oracle.password}" />     </bean>  <bean id="oraclesessionfactory" class="org.springframework.orm.hibernate4.localsessionfactorybean">     <property name="datasource" ref="oracledatasource" />     <property name="entityinterceptor">         <bean class="be.core.dao.interceptor.auditinterceptor"/>     </property>     <property name="hibernateproperties">         <value>             hibernate.temp.use_jdbc_metadata_defaults=false             hibernate.default_schema=             hibernate.dialect=org.hibernate.dialect.oracle9dialect         </value>     </property>     <property name="packagestoscan">         <value>domain</value>     </property> </bean> 

entity :

@entity @table(name = "act") @sequencegenerator(name = "act_seq", sequencename = "act_seq") public class act extends baseentity<long> {      private static final long serialversionuid = -731258565201165908l;      @id     @generatedvalue(strategy=generationtype.sequence, generator = "act_seq")     @column(name="actnum")     private long id;      @notfound(action=notfoundaction.ignore)     @manytoone(fetch=fetchtype.lazy)     @joincolumn(name="socnum")     private enterprise enterprise;      @dateformat(pattern = "dd/mm/yyyy")     @temporal(temporaltype.date)     @column(name="actedate")     private date date;      @column(name = "acte", nullable = false, length = 12)     private string actref; 

code in flow controller :

public act createbaseact(enterprise enterprise, user user) {         act act = new act(enterprise);         act.setwho(user.getwho());         act.setsource(source);         actdao.persist(act);         return act;     } 

when calling persist(), id correctly generated using declared sequence.

at end of flow, commit executed result in error because property actref set after persist() , not tracked :

    debug: org.hibernate.sql - insert act (datcre, majd, version, qui, acte, actedate, socnum, actenopg, actelng, actedrpg, actesrc, actenum) values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?) trace: org.hibernate.engine.jdbc.internal.jdbccoordinatorimpl - registering statement [oracle.jdbc.driver.oraclepreparedstatement@181496]trace: org.hibernate.persister.entity.abstractentitypersister - dehydrating entity: [domain.act#236871950]     trace: org.hibernate.type.descriptor.sql.basicbinder - binding parameter [1] [date] - [mon aug 18 09:35:11 cest 2014]     trace: org.hibernate.type.descriptor.sql.basicbinder - binding parameter [2] [date] - [mon aug 18 09:35:11 cest 2014]     trace: org.hibernate.type.descriptor.sql.basicbinder - binding parameter [3] [integer] - [0]     trace: org.hibernate.type.descriptor.sql.basicbinder - binding parameter [4] [varchar] - [qp]     trace: org.hibernate.type.descriptor.sql.basicbinder - binding parameter [5] [varchar] - [null]     trace: org.hibernate.type.descriptor.sql.basicbinder - binding parameter [6] [date] - [mon aug 18 09:35:11 cest 2014]     trace: org.hibernate.type.descriptor.sql.basicbinder - binding parameter [7] [bigint] - [404371]     trace: org.hibernate.type.descriptor.sql.basicbinder - binding parameter [8] [integer] - [1]     trace: org.hibernate.type.descriptor.sql.basicbinder - binding parameter [9] [varchar] - [null]     trace: org.hibernate.type.descriptor.sql.basicbinder - binding parameter [10] [integer] - [1]     trace: org.hibernate.type.descriptor.sql.basicbinder - binding parameter [11] [varchar] - [6010]     trace: org.hibernate.type.descriptor.sql.basicbinder - binding parameter [12] [bigint] - [236871950]     debug: org.hibernate.engine.jdbc.spi.sqlexceptionhelper - not execute statement [n/a]     java.sql.sqlexception: ora-01400: cannot insert null ("act"."acte") 

some properties set further in flow execution if set property directly after persist(), it's not tracked...

i don't see m doing wrong here, entity should managed. have hint on this?

thank you.

when calling persist(), id correctly generated using declared sequence.

it not possible because have not_null constraint on acte field.

see last line in strace. error correctly states cannot insert null ("act"."acte")

you have set value in actref before persist() object.
