title: Using ClassificationAttributeValueTranslator on impex
body: <p>I'm trying to use the ClassificationAttributeValueTranslator  on an impex. I have some examples with  the class ClassificationAttributeTranslator working but can't make this work. </p>
  
  <pre><code>$productCatalog = myCatalog
  $classificationCatalog = myClassification
  
  $catalogVersion = catalogversion(catalog(id[default = $productCatalog]), version[default = 'Staged'])[unique = true, default = $productCatalog:Staged]
  $clAttrModifiers = system = '$classificationCatalog', version = '1.0', translator = de.hybris.platform.catalog.jalo.classification.impex.ClassificationAttributeValueTranslator, lang = es
  //Q_1001 is the ClassAttributeAssignment ID
  $feature1 = @Q_1001 [$clAttrModifiers];
  //123012 is the product code and
  INSERT_UPDATE  Product; code[unique = true]; $feature1; $catalogVersion
  ; 123012 ; TEST VALUE;
  </code></pre>
  
  <p>I'm getting this error</p>
