Bug in Cross Validation Operator

hi,

previously, I used Performance(Classification) in the old Validation (X-Validation) Operator.

when I activated the cases for performance measures like weighted mean precision, margin, squared error etc. it was showed in the log operator outside the X-Validation.

However, with the new Cross Validation operator, the values of the Performance operator doesn't show anymore... its missing values instead "?"...

I think its a bug...

here is a XML example process with iris data to show the problem..

I could not find the old X-Validation anymore.. therefore the problem should be fixed soon please as I am constructing my wm_FScore out of the wm_Recall and wm_Precision

    Thanks@Fred12, something doesn't look quite right as you pointed out. I have passed this on internally. Thanks!

    @Fred12@Thomas_Ott不是一个永久性的解决方案,但是一个临时workaround is to instead log the performance metric values coming out of the Cross Validation operator directly. You have the option of getting the first 3 in the log parameters.

    See this xml version.
