title: Any idea about this weird type error in Pentaho Data Integration?
body: <p>I have this :</p>
  
  <p><code>Insertion des données dans table some_table.0 - SOME_AUTO_GENERATED_DB_KEY Integer : There was a data type error: the data type of java.lang.Boolean object [true] does not correspond to value meta [Integer]</code></p>
  
  <p>What boolean??? Where do you see a boolean? I have added a trace writing to the step just before this failing inserting step, and I see a perfectly fine integer as value of <code>SOME_AUTO_GENERATED_DB_KEY</code> .</p>
  
  <p>How can this be possible? I am very new to Kettle, if you have any idea or tips it would be awesome.</p>
  
  <p>Here a screenshot of the transformation :</p>
