"Copy series operator does not deliver series to inner operators"

Hello all,

I cannot get the "Copy Series Operator" to behave. In the attached process I am expecting to be able to extract something from the value series but whatever I do I get an error suggesting that there is no data being delivered to the inner operator within the copy series operator.

What am I doing wrong?

    Hi Andrew,
    sorry for that. This operator has been forgotten to be adapted to RapidMiner 5 and isn't working at all.

    We will have to correct this in a future release.

    Just checking - the "copy series operator" seems to have gone away in the latest version. Has it gone for good or might it return in the future?

    Hi Andrew,
    this operator died painfully :) It's simply not necessary anymore: You can use the standard multiplier way to copy time series.
    This old fashioned operator copied the data first and then applied different operators in it's subprocesses. The same can now be reached using a standard multiply and connecting it's output ports appropriate.
    That's why it wasn't converted in the first place.
