Re: uncaught java.lang.indexoutofboundsexception

I already expected my error and it worked fine by removing the = operator.

but unfortunately when I wanted to add the real code expected to be run within the for loop, I have had the same exception, and I also had only 1 displayed item in 2 (so that if I have 10 items, it display only 5 by skeeping every time 1 item), here is the code

              

              for(int i=0; i<nbMenuItems; i++){

MaterialToast.alert("ok"+ subMenuItemsContainer.getWidget(i));

MaterialRow row = new MaterialRow();

MaterialColumn col1=new MaterialColumn( 12, 6, 3);

col1.add(subMenuItemsContainer.getWidget(i));

row.add(col1);

mosaiqueContainer.add(row);

}

}

I really don't understand what is the wrong with my code ???

Hello,

I have a global view in which I have to display a table that its rows depend on the number of lateral submenu Items called 'subMenuItemsContainer'.

I create this method where I just want to show if I get the good item values or not and I call it within the view constructor after the initWidget(uiBinder.createAndBindUi(this)) instruction :

        

public void fillContainer(){

int nbMenuItems = subMenuItemsContainer.getWidgetCount();

for(int i=0; i<=nbMenuItems;i++){

MaterialToast.alert(""+ subMenuItemsContainer.getWidget(i));

}

but when I run the application, I got an empty screen with just displayed toast.

and the uncaught java.lang.indexoutofboundsexception when I open the chrome tool Developer, have you an idea what's wrong with my loop that I even tried to replace with while loop, but I have the same problem.

any idea about what mistake have I commited ???
