BambooUserManager getGroup(String) returns an empty list.


I'm storing tuples of strings in the database (accessing via ActiveObjects).

One of the strings is the username of a bamboo user. When getting the membership of this user I usually call:

com.atlassian.user.User user = getBambooUserManager().getUser(userName);
Pager<Group> groups = getBambooUserManager().getGroups(user);

But sometimes it happens that this call will return an empty list.


When I then check using all known groups:

for(Group g : groups){
            Pager<String> members = getBambooUserManager().getMemberNames(g);
            for(String m : members){
                User user = getBambooUserManager().getUser(m);

and iterating and checking the names of the member the affected user will be in that list of a certain group. But still calling

getBambooUserManager().getGroups(com.atlassian.user.User user)

will return an empty list.

The instance of BambooUserManager is always the same (a static reference in a class).


When I assign groups to the affected user and will double check this at /admin/user/viewUsers.action

everythings looks fine and need and the method getGroups(com.atlassian.user.User user) will return a list (or a pager) whith all assigned usergroups. When I then restart the bamboo server, the problem again occurs that the call of getGroups(User user) will return an empty list.


Best regards

Hi Gonchik,


yeah I'm using now the method getMemberNamesAsList() because I can start with the group names. Propably it helps:


BambooUserManager bum = getBambooUserManager();

ArrayList _groupNames = new ArrayList<String>();

Pager<Group> pager = bum.getGroups();
        Collection<Group> page = pager.getCurrentPage();
        for (Group group : page) {

        while (!pager.onLastPage()) {
            page = pager.getCurrentPage();
            for (Group group : page) {

for(String _groupName : _groupNames){

Group group = bum.getGroup(_groupName);
        List<String> userNamesAsList = bum.getMemberNamesAsList(group);

for (String username : userNamesAsList) {
            User u = bum.getUser(username);
