Cross Validation with Random Forest

Hello there,

I cannot overcome a very simple problem that I have shown in the attached figure.

I want to do CrossValidation with RandomForest.

When I enter the inside of CV;  I cannot get the output of the port (Wei), which gives the weight coefficients of the RF on the left, out of the CV. 

When I do it with data split, I can connect directly to the res port and get it. But I can't get out of CV. I would appreciate it if you could help with this.
