I have been using subpopulations in ECJ 15 and it works very well.  I
have recently been trying to make a modification such that the
subpopulations have different fitness measures specified in the
parameter file.  Perhaps I have this wrong but it seems that when an
individual is transferred from one population it keeps its original
fitness measure whereas I would prefer if it would then adopt the
fitness measure of its new population.  Is there a recommended way to do
this? 

Thanks,
