1:n bidirectional woe

[clarence_chiang]

Hi,

I am creating two CMP entity beans with a 1:n bidirectional relationship:

public class Category ... {

/**
*
* @ejb:relation name="Category-UserAction"
* role-name="Category-Has-UserActions"
*
* @ejb:value-object
* aggregate="UserActionEntityValue"
* aggregate-name="UserAction"
* members="UserActionEntity"
* members-name="UserActionEntity"
* relation="external"
* type="Collection"
* @jboss:target-relation related-pk-field="id"
* fk-column="categoryID"
*/
public abstract Collection getUserActions();

// then the set method ...
}

public class UserAction implements EntityBean {

/**
*
* @ejb:relation name="Category-UserAction"
* role-name="UserActions-belongs-to-Category"
* @ejb:value-object
* aggregate="CategoryEntityValue"
* aggregate-name="Category"
* members="CategoryEntity"
* members-name="CategoryEntity"
* relation="external"
* @jboss:relation related-pk-field="id"
* fk-column="categoryID"
*/
public abstract CategoryEntity getCategory();
}

When I tried to access the UserActionEntity's value object:

UserActionEntity entity = home.findByPrimaryKey( ... );
UserActionEntityValue value = entity.getUserActionEntityValue();

I got a TransactionRollbackLocalException: Reentrant method call detected: UserActionEntity [.1.]

What did I do wrong ? I have tried various things ... play with xdoclet tags ... set xdoclet tag reentrant="true" ... but nothing works.

Thanks for all your help

Having the exact same problem, with same results from tinkering. Did you find an answer to this?

Thanks

Hi !

Your value-object-tags lead to cyclic calls in your entities. So either remove it on the one-side (getUserActions) or on the many-side (getCategory). You can only build up objects TREES with these tags.

HTH,
