Dynamic roster is not working.

i followed the documentation to configure a dynamic roster:

from tigase documentation:

Configuration DynamicRoster implementation class should be configured in the config.tdsl file. As it’s an extension to the PresenceState, PresenceSubscription and Roster plugins classes should be configured either for each plugin:

'sess-man' () {
    'jabber:iq:roster' () {
        'dynamic-roster-classes' = 'class1.tigase.com,class2.tigase.com'
    }
    'presence-state' () {
        'dynamic-roster-classes' = 'classList.rosterImplementation.tigase'
    }
    'presence-subscription' () {
        'dynamic-roster-classes' = 'class2.custom.roster,another.class.dynamicRoster'
    }
}

or globally:

'sess-man' () {
    'dynamic-rosters' () {
        class (class: custom.dynamicRoster.class) {}
    }
}

i did the same:

implement DynamicRosterIfc:

public class CmmsRosterPlugin implements DynamicRosterIfc {

in config.tdsl:

'dynamic-rosters' () {
'sess-man' () {
..
       class (class: com.audiocodes.tigase.CmmsRosterPlugin) {
            'roster-in-e164' = 'true'
           }
    }

..
}

i config i don't see the init function triggers.
