Jens,

thanks for you reply. 

The MVP-2 example (with UIBinder) also uses HandlerManager directly in its 
code, just as the MVP-1.  I shall try my hand, using SimpleEventBus in 
these samples. 

I wonder how HandlerManager got into these samples in the first place. Was 
it a mere oversight, in a series of articles which were focusing on MVP, 
without paying much attention to the choice of EventBus ?  Or, was there 
some evolution over time, resulting in HandlerManager falling out of grace ?  


I'm learning my way through a huge GWT project which has been going for 
years. It carries the scars of multiple paradigm-changes, where the 
preferred design pattern of one year has become the black sheep of the next 
year.  A herd of sheep would be a more accurate analogy for the different 
web pages developed over the years: some black, some grey, and some shining 
white -:)   The romans said "ars longa, vita brevis" so let's enjoy the 
journey.

Andrew
