Steps to reproduce:

1. Add a new siteaccess to app/config/ezplatform.yml ("en" in this test):

ezpublish:
    siteaccess:
        list:
          - site
          - en
        groups:
            site_group:
                - site
                - en
        default_siteaccess: site
        match:
            URIElement: 1
    system:
        ....
        site:
            languages:
                - eng-GB
        en:
            languages:
                - eng-GB

Note: the attached "ezplatform.yml" config file was used in the tests

2. Login to the admin interface;
3. Create a new article ("Test Article" in this test);
4. Click on the "Page" tab.

Expected:

• The two siteaccesses ("site" and "en") have good URLs and allow to switch between both of them

Result:

• The preview URL is correct on the first siteaccess ("site") and the article is previewed correctly:
  http://example.com/ez#/studio/insite/http://example.com/site/Test-article
• The link on the second siteaccess ("en") only has the homepage URL (HOST/en):
  http://example.com/ez#/studio/insite/http://example.com/en/
