Hi everybody,

I get the following exception when I run an etl transformation the second time:

Code:

I am using version 6.0.0.0-353, build 1 of kettle. The only thing I have found on the web that resembles my problem is http://jira.pentaho.com/browse/PDI-8341 that was apparently fixed in version 5.0.0.

Any help is highly appreciated.

Thank you.
