Term panel with mean mode should display 0 other values

[krystiankaluzny]

Hi,
I created term panel with mean mode and I check Other, like this:

And it looks like this:

I expect that Other values bar displays 0 value but it isn't

After some investigation i found that lines in terms/module.js

var sum = 0;
$scope.hits = results.response.numFound;

...

if ($scope.panel.field && $scope.fields.typeList[$scope.panel.field] && $scope.fields.typeList[$scope.panel.field].schema.indexOf("T") > -1) {
          $scope.hits = sum;
}

...

$scope.data.push({label:'Other values',
          // data:[[k+1,results.facets.terms.other]],meta:"other",color:'#444'});
          // TODO: Hard coded to 0 for now. Solr faceting does not provide 'other' value.
          data:[[k+1,$scope.hits-sum]],meta:"other",color:'#444'});

So $scope.hits - sum = $scope.hits cause sum is equals 0

scope.fields.typeList based on /admin/luke?numTerms=0&wt=json respons.
For user_type_str it looks like this

"fields" : {
    "user_type_str": {
      "type": "string",
      "schema": "I-SD-----OF-----l",
      "index": "ITS------OF------",
      "docs": 224736
    },
   ...
},
"info": {
    "key": {
      "T": "Tokenized",
    },
   ...
}

My user_type_str configuration from managed-schema

<field name="user_type_str" type="string" stored="true"/>
<fieldType name="string" class="solr.StrField" sortMissingLast="true" docValues="true"/>

The question is what is the purpose of checking if schema contains "T"?
And if there is some reason for it, how should I change my schema to work with it?
Maybe setting data should set 0 explicity:
data:[[k+1, 0]],meta:"other",color:'#444'}

I use Banana 1.6.0
Note that using count mode works fine couse sum == $scope.hits
