> AttributeBasedRelationDAO class gets NullPointerException when trying to create a relation
between two ldap entities. StackTrace is as follows:
> -----------------------------------------------------------------------------------------------------------------------------
> SEVERE: Servlet.service() for servlet JetspeedContainer threw exception
> java.lang.NullPointerException
> 	at org.apache.jetspeed.security.mapping.ldap.dao.impl.AttributeBasedRelationDAO.internalAddRelation(AttributeBasedRelationDAO.java:165)
> 	at org.apache.jetspeed.security.mapping.ldap.dao.impl.AttributeBasedRelationDAO.addRelation(AttributeBasedRelationDAO.java:230)
> 	at org.apache.jetspeed.security.mapping.ldap.dao.DefaultLDAPEntityManager.addRelation(DefaultLDAPEntityManager.java:88)
> 	at org.apache.jetspeed.security.spi.impl.JetspeedPrincipalLdapAssociationStorageManager.addAssociation(JetspeedPrincipalLdapAssociationStorageManager.java:56)
> ...more
> -----------------------------------------------------------------------------------------------------------------------------
> To fix the problem AttributeBasedRelationDAO class line 164 (internalAddRelation method
body) should be changed from:
> --------------------------------------------
>         if(relationAttribute == null)
>         {
>             fromEntity.setAttribute(this.relationAttribute,new ArrayList<String>());
   
>         }
> --------------------------------------------
> to:
> --------------------------------------------
> 		if (relationAttribute == null)
> 		{
> 			fromEntity.setAttribute(this.relationAttribute, new ArrayList<String>());
> 			relationAttribute = fromEntity.getAttribute(this.relationAttribute);
> 		}
> --------------------------------------------
> Just setting the attribute leaves relationAttribute NULL, causing the NPE.
