Why is my timeline created with django bindings not showing any data?

[mshapirovp]

I have the following django template defined:

{% extends "splunkdj:base_with_app_bar.html" %}    
{% load splunkmvc %}    
{% block title %}{{app_name}}: Test{% endblock title %}    
{% block css %}
    <!-- Style sheets are loaded here -->
    <link rel="stylesheet" type="text/css" href="{{STATIC_URL}}{{app_name}}/custom.css" />
    <link rel="stylesheet" type="text/css" href="{{STATIC_URL}}splunkjs/css/dashboard.css" />
    <style>
    </style>
{% endblock css %}

{% block content %}
    {% timerange id="timerange_range"
             earliest_time="$earlyval$"|token_safe
             latest_time="$lateval$"|token_safe
             preset="Last 7 days"
    %}
    {% timeline id="timeline_requests" managerid="search_exceptions" %}
    {% eventsviewer id="events_results" managerid="search_exceptions" count=5 %}
{% endblock content%}

{% block managers %}
    {% searchmanager
        id="search_exceptions"
        search='index=_internal'|token_safe
        earliest_time="$earlyval$"|token_safe
        latest_time="$lateval$"|token_safe
        preview=True
        cache=True
    %}

{% endblock managers %}

{% block js %}
{% endblock js %}

When I load the page I correctly see data in the event viewer, but I never see any data in the timeline. This is on Splunk 6.1.1.

Anyone have any clues as to why this template doesn't work?

Turns out you have to set the search manager's status_buckets property to a non-zero value.
