[ https://jira.jboss.org/jira/browse/JBSEAM-3704?page=com.atlassian.jira.pl... ] Julien Hattier resolved JBSEAM-3704. ------------------------------------ Fix Version/s: 2.1.0.SP1 Resolution: Done So, the problem had is Origin in the JpaIdentityManager, line 425 : Collection roleGroups = (Collection) roleGroupsProperty.getValue(targetRole); My Entity was define with the following statement for the RoleGroups Property : @RoleGroups @ManyToMany(targetEntity = org.summerschool.entities.security.Role.class) @JoinTable(name = "RoleGroups", joinColumns = @JoinColumn(name = "RoleId"), inverseJoinColumns = @JoinColumn(name = "GroupId")) private Set<Role> groups; I had to initialize the field like this : private Set<Role> groups = new HashSet<Role>(); It solved the issue easily. But maybe someone can modify the JpaIdentityManager in order to tolerate this. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
