ImageFormatter::viewElements() does:

  $url = NULL;
  if ($image_link_setting == 'content') {
      $entity = $items->getEntity();
      if (!$entity->isNew()) {
        $url = $entity->urlInfo();

(accounts for node preview - the parent node doesn't have a URL yet)

ResponsiveImageFormatter::viewElements() doesn't bother:

  $url = NULL;
  if ($this->getSetting('image_link') == 'content') {
    $url = $items->getEntity()->urlInfo();

But Entity::urlInfo() throws an Exception if the entity isNew() :-)

Patch fixes changes ResponsiveImageFormatter to do the same as ImageFormatter.
I guess that logic could be moved up to a separate helper method in ImageFormatterBase, not fully sure that's really worth it...

Also, this will need tests...

For test inspiration: see \Drupal\image\Tests\ImageFieldDisplayTest::_testImageFieldFormatters(), specifically this bit:

    // Ensure that preview works.
    $this->previewNodeImage($test_image, $field_name, 'article');

Should be added to \Drupal\responsive_image\Tests\ResponsiveImageFieldDisplayTest().

With help from nelllaparedes and joosuuee, we did manual testing of the patch from #1. Results are good, Drupal breaks when trying to preview a node with an image field using a responsive image formatter (linked to 'content' in "manage display" options for the content type); the patch fixes the issue as expected .

Testing steps:

  1. Got a new env for D8 (standard profile) and installed Drush 7 with Composer.
  2. Enabled responsive images module with drush: drush en -y responsive_image.
  3. Created a new responsive image style, using the default image styles for the three breakpoints.
  4. We set the Responsive Image formatter for the Image field in the display options for the Article content type, also enabling the option to link to content (this last one setting is required to induce breakage).
  5. Browsed to /node/add/article, populated basic fields and chose an image for the Image field.
  6. Clicked the "preview" button and the site broke, stating that an error occurred (no details about the error were displayed).

After applying the patch, the same steps as above didn't give us an error. The node preview displayed just normally.

These screenshots show the two states (broken/fixed):

@jedihe: thanks for the screenshots and detailed steps to reproduce !

However, "Needs tests" more specifically means adding testing code in our test suite so that the behavior is automatically tested against potential regressions later.

Thus, the correct issue status is "needs work" atm, until those tests are added to the patch. Will try to work on that, but can't honestly say it's on the top of my list, so anyone is more than welcome to pick it up.

(and thanks a lot @Wim for the pointers in #2, finding the right place for new tests to fit given the size of our test suite can be a bit daunting...)

Also, @jedihe++ for the inception-style screenshots :-p

:D Apologies for not using the right status.

After our testing, we worked with @dalguete to get a test (following Wim's excellent suggestion). Our guesswork got us a few steps forward, but not to a working version.

Finally managed to get the test working as needed: it fails without the fix in place, and the fix makes it pass. Let's see what our helpful bot has to say.

The test was written jointly with @dalguete.

Just learned on IRC that I must switch to Needs Review for the bot to see the patches. I'm reattaching the files, too.

Files are exactly the same as in #10, interdiff is against patch in #1.

The last submitted patch, 11: 2424697-ResponsiveImageFormatter_preview-11-TEST-ONLY.patch, failed testing.

Well, we have a working prototype for the test. Now we need a reviewer to provide suggestions on how to refactor/polish it in order to achieve the required quality for committing.
