[Qgis-developer] Error in Processing MOdeller?

[Paolo Cavallini]

Hi all.
Following the training Processing manual, modeler_hydro_calculator.rst,
I have a problem in adding reslts from Calculator: I add the suggested
formula, but when closing the popup all the connecting lines are
disappeared, and the calculation is gone.
Anyone confirms?
All the best.
