Fatal error: Unsupported operand types in fivestar.field.inc on line 353 [#1268972]

As a site admin in the View UI, if I add a field to the view that is a fivestar field, I get the following AJAX error:

An AJAX HTTP error occurred.
HTTP Result Code: 200
Debugging information follows.

XDEBUGGING the code prior to line 353 of the fivestar.field.inc:

<?php
  if ($instance['widget']['type'] == 'exposed') {  // line 349
    $entity_info = entity_get_info($instance['entity_type']);  // <-- this returns NULL
    // Include "Default" in the list of view modes to match the ones displayed
    // to the user; see field_ui_menu().
    $view_modes = array('default' => array('label' => t('Default'))) + $entity_info['view modes'];  // Line 353, fails because $entity_info is NULL
    $bundles = field_info_bundles($instance['entity_type']);

    $element['expose'] = array(
      '#type' => 'checkbox',
      '#title' => t('Expose this Fivestar field for voting in the @display display on the @type type.', array('@display' => $view_modes[$view_mode]['label'], '@type' => $bundles[$instance['bundle']]['label'])),
      '#default_value' => $settings['expose'],
      '#return_value' => 1
    );
  }
?>

I am not sure what the func entity_get_info is supposed to provide. But ignoring it, and only adding the defaults, the widget seems to act fine. So, this may not be the final solution, but it gets me into the ballpark to complete my project:

<?php
// change the following, starting at line 349 on includes/fivestar.fields.inc
  if ($instance['widget']['type'] == 'exposed') {
    $entity_info = entity_get_info($instance['entity_type']);
    // Include "Default" in the list of view modes to match the ones displayed
    // to the user; see field_ui_menu().
    if (is_array($entity_info)) {
      $view_modes = array('default' => array('label' => t('Default'))) + $entity_info['view modes'];
    }
    else {
      $view_modes = array('default' => array('label' => t('Default')));
    }
    $bundles = field_info_bundles($instance['entity_type']);

    $element['expose'] = array(
      '#type' => 'checkbox',
      '#title' => t('Expose this Fivestar field for voting in the @display display on the @type type.', array('@display' => $view_modes[$view_mode]['label'], '@type' => $bundles[$instance['bundle']]['label'])),
      '#default_value' => $settings['expose'],
      '#return_value' => 1
    );
  }
?>

I'm having the same problem but neither of these patches work for me. The error message I get logged is classified under "Theme" and the content is: "MESSAGE Theme key "fivestar_widget" not found."

The implication (I think this is related) is that I get:

"Undefined property: stdClass::$subject in include()" and

"Trying to get property of non-object in block_block_view()"

in the blocks which use Fivestar. This may be because there is some of the widget still sitting in the database somewhere(?). But I'm not sure.

Can anyone help please?

Thanks

@swfindlay please try to keep the comments related to the issues. Sidetracking the issue isn't going to help anyone. Now regarding you error message please see #1268356: Theme key "fivestar_widget" not found. issue which I opened and fixed already.

@jghyde can you explain more regarding your views? I'm not really sure why entity_get_info is returning null, but I'm guessing the the fields instance settings might be missing. Maybe going in the node field settings and re-saving the field should fix it. Usually this happens when the field isn't completely saved with all the expected settings. Also please see issue #1224700: Remove custom views formatters regarding the issues with views.
