編集：解決しました。この質問をした時点では、Magento Cloud Connector は古すぎて Magento 1.7 で動作しませんでした。

Magento クラウド コネクタを使用して製品の更新を行おうとしています。私のxmlは次のようになります。

<magento:update-product config-ref="testConfig" doc:name="Update Product" productSku="#[header:OUTBOUND:ProductId]">
    <magento:catalog-product-entity name="#[header:outbound:Name]">
    </magento:catalog-product-entity>
    <magento:additional-attributes>
        <magento:additional-attribute key="isbn" value-ref="#[header:OUTBOUND:ISBN]" />
        <magento:additional-attribute key="subject" value-ref="#[header:OUTBOUND:Subject]" />    
    </magento:additional-attributes>        
</magento:update-product>

更新を実行しようとすると、常に次の例外が発生します。

org.mule.api.transformer.TransformerException: Could not find a transformer to transform "SimpleDataType{type=java.lang.String, mimeType='*/*'}" to "SimpleDataType{type=com.magento.api.AssociativeEntity, mimeType='*/*'}".

コメントに記載されているように、問題は、値を文字列からAssociativeEntityに変換しようとして失敗する追加の属性ブロックにあると思います。APIサンプルには追加の属性が定義されていないため、追加の属性を定義するための正しい構文が何であるかについてはよくわかりません。

編集: value-ref から value に変更すると、トランスフォーマーの問題は解決しましたが、根本的な問題は解決しませんでした。Masse が以下で指摘したように、コネクタは古すぎる wsdl を使用します。
