Vertical Tabs required fields focuses wrong tab on validation

This is the fist issue I have created. I hope I am doing this correctly. :)

Having looked at the js that gives focus i have a suggested fix:

- in field_group.js change the following code

/**
 * Implements Drupal.FieldGroup.processHook().
 */
Drupal.FieldGroup.Effects.processTabs = {
  execute: function (context, settings, type) {
    if (type == 'form') {
      // Add required fields mark to any fieldsets containing required fields
      $('fieldset.vertical-tabs-pane', context).once('fieldgroup-effects', function(i) {
        if ($(this).is('.required-fields') && $(this).find('.form-required').length > 0) {
          $(this).data('verticalTab').link.find('strong:first').after($('.form-required').eq(0).clone()).after(' ');
        }
        if ($('.error', $(this)).length) {
          $(this).data('verticalTab').link.parent().addClass('error');
          Drupal.FieldGroup.setGroupWithfocus($(this));
          $(this).data('verticalTab').focus();
        }
      });
    }
  }
}

to this

/**
 * Implements Drupal.FieldGroup.processHook().
 */
Drupal.FieldGroup.Effects.processTabs = {
  execute: function (context, settings, type) {
    if (type == 'form') {
      // Add required fields mark to any fieldsets containing required fields
      var errorFocusSet = false;
      $('fieldset.vertical-tabs-pane', context).once('fieldgroup-effects', function(i) {
        if ($(this).is('.required-fields') && $(this).find('.form-required').length > 0) {
          $(this).data('verticalTab').link.find('strong:first').after($('.form-required').eq(0).clone()).after(' ');
        }
        if ($('.error', $(this)).length) {
          $(this).data('verticalTab').link.parent().addClass('error');
          if (!errorFocusSet) {
            Drupal.FieldGroup.setGroupWithfocus($(this));
            $(this).data('verticalTab').focus();
            errorFocusSet = true;
          }
        }
      });
    }
  }
}

I have yet to learn how to make git patches so if someone thinks this is a worthwhile change (or has something better) maybe they could create a patch?

I have just looked at dev 7.x-1.x-dev and noticed this has been fixed in exactly the way I have outlined above. I'll leave this here in case anyone needs a fix for 7.x-1.4

Please mark as fixed.
