i did it.. it is called by himself..

Sure, but when? and how many times?

 

i follow all the process step by step and at the end of the clickHandler it goes in dispatchEvent(event, handler) of SimpleEventBuss.class and it returns to the onClick of my project.. What can i do?

I honestly have no idea, given the code snippets you showed. But put a breakpoint on your addClickHandler and see when it's being called, and where it's called from (look at the call stack in your IDE)

i don't understand your answer.. how can i call an addClick handler of a table in 2 different tab?

I suspect you're calling addClickHandler each time you switch tab. Just try to do it once only.

its a long code, however in summary:

in tab1 i've a table (table1) with a clickHandler that depends from another table (table2)

in tab2 i've only display some db data

code when i switch tab

if (tabLayoutPanel.getSelectedIndex() == 0) { // tab1

build_tab1();

clear_TAB2();

tabLayoutPanel.setSize("100%", "1245px");

}else if (tabLayoutPanel.getSelectedIndex() == 1) { // tab2

build_tab2();

clear_TAB1();

tabLayoutPanel.setSize("100%", "1245px");

}

code tab1

table1.addClickHandler(new ClickHandler() {

public void onClick(ClickEvent event) {

               

              bool t = Window.confirm("continue?")

              if(t && is a radioButton in table2 checked??)

                        server call for db data

                        table1.settext(r,c,"something i need");

             else

                       Window.alert("select something in table2");

        }

});

now the problem is that if i change tab and i return in tab 1 the code in onClick() is runned n time where n is the number of times that i switched tab
