Jira issue originally created by user sebastian.hoitz:

I have a class App_Model_Contact_Attribute:

App*Model_Contact*Attribute:
  type: mappedSuperclass
  inheritanceType: SINGLE_TABLE
  table: contact_attribute
  discriminatorColumn:
    name: type
    type: string
    length: 20
    columnDefinition: "varchar(20) not null"
  discriminatorMap:
      emailAddress: App*Model_Contact*EmailAddress
      twitterAccount: App*Model_Contact*TwitterAccount
  id:
    id:
      type: integer
      columnDefinition: "int unsigned not null auto_increment"
      generator:
        strategy: AUTO
  fields:
    value:
      type: string
      notnull: true
      columnDefinition: "varchar(45)"
  manyToOne:
    contact:
      joinColumn:
        name: contactID
        referencedColumnName: id
        columnDefinition: "int not null unsigned"
      targetEntity: App*Model*Contact
      fetch: EAGER
      cascade: [persist]

and a class App_Model_Contact_EmailAddress and App_Model_Contact_TwitterAccount. Both yml files look similar to this:

App*Model_Contact*TwitterAccount:
  type: entity

Now, when I want to execute migrations:diff it always fails giving me the message: "Table contact_attribute already exists".

This probably has to do with the mappedSuperClass declaration in my models.
