"[Solved] Windowing operator returns just 0"

qwertz

Good evening,

The following process seems to be correct to me but after windowing, all examples of the label attribute are "0". Please help!!!
If you enable the set role operator it works. So it seems that is something with the combination of windowing operator and the "id" role.


Best regards
Sachs

PS: In my original file I used dates as an id but with the same result.

Hi Sachs,

please update both RapidMiner and the Series Extension to the latest version and try again. Do you still have this problem? There has been performed quite some work on the Windowing operator.

Best regards,
Marius

That's it! I haven't seen that there is a new version so far. Lucky me, seems that my problem has been fixed just a few days before I discovered that it is there

Cheers
