View_mode column not created using Features

[sumachaa]

When using features module in creating the field instance which is configured with er_viewmode, the view mode column is not getting created.

This works fine when the field is updated from the Drupal admin UI

Attached a simple feature which can be used for testing basic_page.zip

Steps to replicate the issue

• Create a new field in any content type using entityreference as the field type
• Update this field to use er_viewmode
• Export the field settings using a feature
• Deploy the feature in another site and enable the feature

Now we can see that the field_instance got created, and it is tagged as using er_viewmode behavior, but when you get the Database schema for this field, you can notice that the view_mode column is not created. Because of this when you create a new page for the content type it throws error that column does not exist.

It works fine when we save the field settings once.

The issue seems to be that the class ERViewModeBehavior is not getting loaded & hence the function ctools_plugin_get_class returns NULL.

Loading the class file explicitly resolves this issue.

As per step 3 here https://www.drupal.org/node/1962284 it is good to load the class files from info.

Closing the issue as the code is merged
