I'm facing a "deadloop" problem with the valueobjects of an M:N relationship beans.
When loading the valueobject of bean A, it load the valueobject of bean B which try to load a valueobject of bean A and so on.
JBoss throws a "Reentrant method call detected" from the EJBException.
The problem is between a Person and a Task (each Person can have M Task where he is involved in and a Task can concern N Person.
PersonValue should have a Collection of Task and TaskValue a Collection of Person.
This is done by an hardcoded relation table with the following design : TaskToPerson *IdTaskToPerson IdTask IdPerson
The beans have this description :
<TaskBean>
/**
* @ejb.relation
* name="PERSON-TASK"
* role-name="task-concern-person"
* target-ejb="ejbPerson"
* target-role-name="person-involvedin-task"
* @ejb.interface-method
* view-type="local"
* @jboss.relation-mapping
* style="relation-table"
* @jboss.relation-table
* table-name="TaskToPerson"
* create-table="false"
* remove-table="false"
* @jboss.relation
* related-pk-field="id"
* fk-column="IdPerson"
* @ejb.value-object
* aggregate="org.TechAdvantage.intranet.ejb.cmp.PersonValue"
* aggregate-name="Person"
* members="org.TechAdvantage.intranet.ejb.cmp.PersonLocal"
* members-name="Person"
* relation="external"
* type="Collection"
*/
public abstract java.util.Collection getPersons();
</TaskBean><PersonBean>
/**
* @ejb.relation
* name="PERSON-TASK"
* role-name="person-involvedin-task"
* target-ejb="ejbTask"
* target-role-name="task-concern-person"
* @ejb.interface-method
* view-type="local"
* @jboss.relation-mapping
* style="relation-table"
* @jboss.relation-table
* table-name="TaskToPerson"
* create-table="false"
* remove-table="false"
* @jboss.relation
* related-pk-field="id"
* fk-column="IdTask"
* @ejb.value-object
* aggregate="org.TechAdvantage.intranet.ejb.cmp.TaskValue"
* aggregate-name="Task"
* members="org.TechAdvantage.intranet.ejb.cmp.TaskLocal"
* members-name="Task"
* relation="external"
* type="Collection"
*/
public abstract java.util.Collection getTasks();
</PersonBean>I don't see obvious errors and I really don't see why this deadloop occurs as the relationtable should keep this clean.
Thanks for your help, ionel
