}

you have 2 ways :

first 1 :

extends selectorcomposer

wiring components :

listbox lbthree; textbox pepito; button savebutton;

change :

@wire private listbox lbthree; @wire private textbox pepito; @wire private button savebutton;

second create right @listen :

@listen("onclick = #savebutton")

second 1 :

keep genericforwardcomposer : public void onclick$savebutton(event event) { //... }

edit : corrected @nabila. comment.
