title: Symfony 1.4, Propel, build-forms use an older yaml?
body: <p>I use Symfony 1.4 with Propel. I deleted a table (name: company_show_field), deleted from database and schema.yml too. Then I added a new table named agency_company (it is exists in DB too). So I have this now:</p>
  
  <pre>
    company:
      _attributes: { phpName: EdimaCompany }
      id: { type: INTEGER, size: '11',  autoIncrement: true, required: true }
      name: { type: VARCHAR, size: '100', required: true }
      ...
  
    agency_company:
      _attributes: { phpName: EdimaAgencyCompany }
      _propel_behaviors:
        symfony:
          form: false
          filter: false
      agency_id: { type: INTEGER, size: '11', required: true, primaryKey: true, foreignTable: company, foreignReference: id, onDelete: CASCADE }
      company_id: { type: INTEGER, size: '11', required: true, primaryKey: true, foreignTable: company, foreignReference: id, onDelete: CASCADE }
  </pre>
  
  <p>Then I did:</p>
  
  <pre>
  symfony cc
  symfony propel:build-model
  symfony propel:build-forms
  </pre>
  
  <p>but the BaseEdimaCompanyForm class throws an exception: "Call to undefined method BaseEdimaCompany::getEdimaCompanyShowFields". I deleted some lines from this file (to test the generation is make a new file), and regenerate the models/forms again, but symfony generated a bad code again.</p>
  
  <p>I'm sure this table (company_show_fields) isn't exists in the schema and in the DB. And I don't see the new table in this form class (agency_company).</p>
  
  <p>Can somebody help me please? Why this happen? Where can symfony get the table name, what not exists?</p>
  
  <p>PS: sorry for my English, this is not my native language.</p>
