RooFormulaVar does not change value after fit

Hi all,

I have a RooFormulaVar which depends on some floating parameters of the fit.

This RooFormulaVar does not get updated after the fit, even though I’m sure its companion floating parameter is changing (i.e. when I call getValV() its value is the same as before the fit).

Might this be due to the fact that this RooFormulaVar and the companion floating paramater come from different workspaces ? What workaround would you suggest to solve this problem (which is not to calculate manually the new RooFormulaVar value after fit) ?
