Hi, I am trying to run some simple range checks on sensor data coming from a DataTurbine actor. I.e. filtering out those -99999 values and replacing them with NULL. I have managed to replace them with nil and that works well for graphing the data in Kepler, but I can't insert the data into a database. The RecordAssembler seems to take 'nil' as a string. The expression s.equals(nil)?null:s works in the expression evaluator (i.e. returning object(null) when true) but returns always false when I put it into an expression actor.
What am I missing here? The workflow is attached, although it won't work because I have the DT instance running on my localhost. thanks Corinna -------------- next part -------------- A non-text attachment was scrubbed...
