We are encountering the same issue... the node appears to execute correctly (we get a green light), but the console sends out a "ERROR SDFParserModel", and the CDK cell is empty. I sent you separately a knime.log from my workflow.
Thorsten told me it is a bug caused by empty names in the connection table.
Using names indeed solves the problem. It will be fixed in the 1.3.3 release scheduled for mid-January.
