Steps to reproduce:

1. Create new content class:

Name: Profile
Identifier: profile

Add one attribute:

Attribute Type: Text line

• Name: Title
• Identifier: title
• Is required: checked
• Searchable: checked

2. Create a new content in content tree for the new class. Called it "Jeune Journaliste":

Home
	Tests
		Jeune Journaliste

3. Duplicate "Article" class, and add a new attribute of type "Object relations" to the new class. The new class is called "Article 2", and the new attribute is called "Profiles":

Name: Article 2
Identifier: article_2

Attribute Type: Object relations

• Name: Profiles
• Identifier: profiles
• Selection method: List with checkboxes
• Allowed classes: profile
• Is required: not checked
• Searchable: checked
• Default location: Tests

4. Create a content for the new "article_2" class. Called it "13140 Test 1", and associated "Jeune Journaliste" content defined in step 2 to the "profile" object relations attribute:

Home
	Tests
		13140 Test 1

5. On Solr admin interface, execute this query:

/select?q=*:*&fq=meta_class_identifier_ms:article_2&wt=json&indent=true&facet=true&facet.field=attr_profiles_t

Result:

{
  "responseHeader": {
    "status": 0,
    "QTime": 8,
    "params": {
      "q": "*:*",
      "facet.field": "attr_profiles_t",
      "indent": "true",
      "fq": "meta_class_identifier_ms:article_2",
      "wt": "json",
      "facet": "true",
      "_": "1423594692695"
    }
  },
  "response": {
    "numFound": 1,
    "start": 0,
    "docs": [
      {}
    ]
  },
  "facet_counts": {
    "facet_queries": {},
    "facet_fields": {
      "attr_profiles_t": [
        "jeun",
        1,
        "journalist",
        1
      ]
    },
    "facet_dates": {},
    "facet_ranges": {},
    "facet_intervals": {}
  }
}

This is not correct, since the values of "attr_profiles_t" are truncated - "jeun" should be "jeune", and "journalist" should be "journaliste".
