thx, added some users and groups over the api.. adding users works but adding groups failes.. without any exception. IdentityService ids = processEngine.getIdentityService(); ids.createGroup("salesmanager", "salesmanagertyp", "manager"); ids.createUser("tina", "Tina", &quot;Family&quot;,&quot;tina(a)firm.com&quot;); ids.createMembership("tina", "salesmanager"); <- this causes an "group doesnt exist" exception... realy strange even cant add a group and find it later over id, simply doesnt exist.
