I think you mean add a getter and setter in CompositePanel, but the problem
is how to access it in HATestPanel?
as I don't know the variable name of each CompositePanel.
just like I click the button three times, then what is the variaible name
of these 3 compositePanel? although in each click handler its name is
compositePanel.
