Fixed version (ground truth):

    iErrorManager.clearManageConnectionsWarn();
    refreshOperationAreaEnable(true);
    List<ConnectionBean> storedConnections=connectionsDialog.getConnections();
    if (storedConnections == null || storedConnections.isEmpty()) {
      defaultConnectionBean=LoginHelper.createDefaultLocalConnection();
      storedConnections=new ArrayList<ConnectionBean>();
      storedConnections.add(defaultConnectionBean);
      LoginHelper.getInstance().setStoredConnections(storedConnections);
      LoginHelper.getInstance().saveConnections(storedConnections);
      setRepositoryContextInContext();
    }
 else     if (storedConnections.size() == 1) {
      defaultConnectionBean=storedConnections.get(0);
      if (defaultConnectionBean.isComplete()) {
        LoginHelper.getInstance().setStoredConnections(storedConnections);
        LoginHelper.getInstance().saveConnections(storedConnections);
        if (LoginHelper.isRemoteConnection(defaultConnectionBean)) {
          try {
            gotoNextPage();
            return;
          }
