Fatal error: Call to a member function ensure_my_table() on a non-object

This also occurs if you have a display with overridden fields and a not overridden combined fields filter where some of the fields that are used by the filter have been removed by the override.

Easy to reproduce with just Views 3.8 and D7 Core and the following View (no field access modules needed):

$view = new view();
$view->name = 'test_combined_field_filter';
$view->description = '';
$view->tag = 'default';
$view->base_table = 'node';
$view->human_name = 'Test combined field filter';
$view->core = 7;
$view->api_version = '3.0';
$view->disabled = FALSE; /* Edit this to true to make a default view disabled initially */

/* Display: Master */
$handler = $view->new_display('default', 'Master', 'default');
$handler->display->display_options['title'] = 'Test combined field filter';
$handler->display->display_options['use_more_always'] = FALSE;
$handler->display->display_options['access']['type'] = 'perm';
$handler->display->display_options['cache']['type'] = 'none';
$handler->display->display_options['query']['type'] = 'views_query';
$handler->display->display_options['exposed_form']['type'] = 'basic';
$handler->display->display_options['pager']['type'] = 'full';
$handler->display->display_options['pager']['options']['items_per_page'] = '10';
$handler->display->display_options['style_plugin'] = 'table';
$handler->display->display_options['style_options']['columns'] = array(
  'title' => 'title',
);
$handler->display->display_options['style_options']['default'] = '-1';
$handler->display->display_options['style_options']['info'] = array(
  'title' => array(
    'sortable' => 0,
    'default_sort_order' => 'asc',
    'align' => '',
    'separator' => '',
    'empty_column' => 0,
  ),
);
/* Field: Content: Title */
$handler->display->display_options['fields']['title']['id'] = 'title';

$handler->display->display_options['fields']['created']['date_format'] = 'long';
$handler->display->display_options['fields']['created']['second_date_format'] = 'long';
/* Field: Content: Published */
$handler->display->display_options['fields']['status']['id'] = 'status';
$handler->display->display_options['fields']['status']['table'] = 'node';
$handler->display->display_options['fields']['status']['field'] = 'status';
$handler->display->display_options['fields']['status']['not'] = 0;
/* Sort criterion: Content: Post date */
$handler->display->display_options['sorts']['created']['id'] = 'created';
$handler->display->display_options['sorts']['created']['table'] = 'node';
$handler->display->display_options['sorts']['created']['field'] = 'created';
$handler->display->display_options['sorts']['created']['order'] = 'DESC';

$handler->display->display_options['filters']['status']['expose']['operator'] = FALSE;
/* Filter criterion: Global: Combine fields filter */
$handler->display->display_options['filters']['combine']['id'] = 'combine';
$handler->display->display_options['filters']['combine']['table'] = 'views';
$handler->display->display_options['filters']['combine']['field'] = 'combine';
$handler->display->display_options['filters']['combine']['operator'] = 'contains';
$handler->display->display_options['filters']['combine']['expose']['operator_id'] = 'combine_op';
$handler->display->display_options['filters']['combine']['expose']['label'] = 'Combine fields filter';
$handler->display->display_options['filters']['combine']['expose']['operator'] = 'combine_op';
$handler->display->display_options['filters']['combine']['expose']['identifier'] = 'combine';
$handler->display->display_options['filters']['combine']['fields'] = array(
  'title' => 'title',
  'nid' => 'nid',
  'created' => 'created',
  'status' => 'status',
);

/* Display: Page */
$handler = $view->new_display('page', 'Page', 'page');
$handler->display->display_options['path'] = 'test-combined-field-filter';

/* Display: Bugged page */
$handler = $view->new_display('page', 'Bugged page', 'page_1');
$handler->display->display_options['defaults']['fields'] = FALSE;
/* Field: Content: Title */
$handler->display->display_options['fields']['title']['id'] = 'title';

$handler->display->display_options['path'] = 'test-combined-field-filter/bugged';

On the URL test-combined-field-filter/bugged you will get the error

Patch applied cleanly and solved the bug.

Maybe update the comment in the patch to reflect that multiple scenario's can cause the field to not be available?

Worked for me too.

Ditto. Worked for me also. Thanks!

When I clicked on a node (so just viewing as user1/admin) then I had error:

Fatal error: Call to a member function ensure_my_table() on a non-object in /home/techniek/public_html/sites/all/modules/views/handlers/views_handler_filter_combine.inc on line 60

So my case was somewhat different from the ones in this issue. Bud I applied the patch and the error is gone!

Thanks!

I had the same error as marchellodepello, patch in #1 solved it for me as well.

+1 to this patch, it's working well for me.

Patch #1 worked for me as well. Thank you!

Tout pareil : Patch #1 worked for me as well. Merci ! :-)

Confirming that this patch fixes the scenario in #2.

@jhedstrom best approach that I know:

1. open a drupal core project issue,
2. with a VDC tag
3. Views component for 8.0.x version
4. Assign this issue as a related issue.
5. Submit a patch

To get it in faster... write a test that proves the bug, preferably UnitTest but WebTest can do the trick. Post the tests only and have testbot fail and then the combo(tests+fix) showing it fixes the issue.

All assuming this bug still exists in D8.

Opened a D8 issue for this with a port of patch in #1 with added testing.

Ok the referencing is smart enough, so didn't have to add it here

Patch #1 worked for me. I encountered it with dev, the recommended release doesn't throw errors.

That totally makes sense. Committed to 7.x-3.x and pushed

This is the commit to D7 http://cgit.drupalcode.org/views/commit/?id=d7837bc
Form \Drupal\views\Plugin\views\filter\Combine in D8

    // Only add the fields if they have a proper field and table alias.
    foreach ($this->options['fields'] as $id) {
      // Overridden fields can lead to fields missing from a display that are
      // still set in the non-overridden combined filter.
      if (!isset($this->view->field[$id])) {
        // If fields are no longer available that are needed to filter by, make
        // sure no results are shown to prevent displaying more then intended.
        $this->view->build_info['fail'] = TRUE;
        continue;
      }

So it seems it's already fixed.

Yeah this was fixed for D8 in #2370251: Removed fields in Views Combined Filter setting lead to Fatal error.

Having a strange recurrence of the same on views 7.x-3.11 and specifically on views field view , both dev and 7.x-1.1 versions. I tried applying the patch to views but nothing changes.
Strangely, I get this error on about 8 node items of a 46 nodes custom content type, started arbitrarily, and randomly around the time I was playing with openlayers. Since then has not resolved.

this was a rare case for me, I am using Views Field View which allows you to embed another view within a view...

Long story short, I deleted the view that was being embed and didn't remove it from master view... just in case someone rolls into this problem!

okay, patch worked for me also

This error showed on a logged-in Drupal user's view page (it was a table of nodes, using a combined filter as a 'searchbox of sorts'). Only her computer - I couldn't reproduce. Simply deselecting all the fields in the combined filter caused her error to go away. I was able to re-select those fields, and the error message didn't come back. Hopefully this quick fix saves some of you some time.

This issue is closed. If that's an error and there still is the original issue, please re-open this issue. If there is a different problem, please open a new issue. It's unlikely anyone will see comments on a closed issue.

Sorry a stupid question, but how exactly do you apply this patch? Do you make a new file? If so what is the name of that file and if not where do I include the code of the patch in my views_handler_area_text.inc - file? Or do I include it even into a different file?

Thank you very much in advance!

@Drupal_8_TTerm you don't need to apply this patch, this was fixed in Drupal 7 Views and Drupal 8 core. So if you still run into this on an up-to-date install, please open a new issue for this.
