Serialization problem

I take liberty to forward a bug  report we received from a customer.

Apparently under some circumstances the Indigo code fails to save properly. Workflow is attached and the error is:

Caused by: java.io.NotSerializableException: java.nio.HeapByteBuffer
at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1184)
at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:1548)

Workflow attached.

Hi Bernd,

thank you for the report. I found this is a problem on KNIME's side. And added report with a way to resolve here.

Best regards,

Anton

Thanks! It seems Thorsten has picked it up.
