Error when viewing translation revision "Fatal error: Call to a member function bundle() on string"

This error occurs because when you're trying to view node revision, variable $variables['node'], passed into template_preprocess_page, is not an object. It's a string within current node ID. So, to fix this error I've added a check whether the variable $variables['node'] is an object. And if it's not, then this object is loaded by ID.

Above patch will still fail if you try to view a revision of a non-existing node id.

Also I think the correct function to add this suggestion would be "zurb_foundation_theme_suggestions_page_alter"

This seems like an important bug to fix, I'm bumping the priority.

@tim_dj Can you explain why array_splice is being used here instead of the previous operation ($suggestions[] = ...)?

Otherwise the sequence of suggestions would be out of order:

array_splice

Array
(
    [0] => page__node
    [1] => page__node__product
    [2] => page__node__%
    [3] => page__node__10657
)

$suggestions[]

Array
(
    [0] => page__node
    [1] => page__node__%
    [2] => page__node__10657
    [3] => page__node__product
)

Thank you @tim_dj! Committed to the 6 and 5 branches.

This is not related to the ZURB foundation theme, but I am posting this for others who find this issue, looking for help with PHP Fatal error: Call to a member function bundle() on string:

I just want to add you have to careful with this - I just got stung where \Drupal::routeMatch()->getParameter('node'); will return an array of 1 item (the node id) on node revision delete pages, so if you calling a method on what you assume to be an object you will get a fatal error like "Fatal error: Call to a member function getType() on string". – Jeff Burnz Aug 10 at 1:13

To be sure you have really a node you can use "if ($node instanceof \Drupal\node\NodeInterface) " condition. (see drupal.org/docs/8/api/entity-api/working-with-the-entity-api‌​) – tdd Nov 28 at 7:48

I couldn't get the suggestions on the "Working with the Entity API" page to work, but making sure that revisions wasn't present in the URL seemed to do the trick:

if (($node = \Drupal::routeMatch()->getParameter('node')) && (strpos($_SERVER['REQUEST_URI'], "revisions") == false)) {
  ...
}

@ressa, Thank you so much! This saved me.
