Hi Dima,

I found some issues.

First: I fixed the FitAll() to also fit the head of the decay tree. It was a "logic bug", just update (at least rho).
Second: In your special case Fit() would have sufficed as you only have one decay node in your etac_vtx candidate list.
Third: When selecting your best kaons you tried to access the Fit() of a fitted kaon (etacfit has the fitted daughters), giving you the null pointer.
Fourth: After fixing these things I got more errors in the block which was never reached before. I leave that to you to fix. Wink
