Re: Can't remove 0 index in ArrayList
You're right, I'm gonna redo all my views with UiBinder, it'll be a good
time to take a deeper look into this.
Thanks again for your comments

Re: Can't remove 0 index in ArrayList
I think you should take some time to find out what the problem is/was.
it's quite unlikely that something in the GWT code changed, so that
such a simple thing would stop working.
Maybe you just had different data before.
Thus it may be an indication that you got something wrong in your
code - difficult to say what when you can't reproduce it.
maybe you got some of your hashCode/equals functions wrong which
could lead to strange behaviour like this.
however, if it's a project that's not critical or if you
just feel fine with this, don't waste your time :)

Re: Can't remove 0 index in ArrayList
Yeah, but the thing is that code was working fine prior to gwt 2.0, so I
just don't understand why lol
Anyway I also tried a simple example like yours and it was working fine, so
I just gave up finding a solution to a problem that I alreay resolved by
doing the alternative way.
Thanks

Re: Can't remove 0 index in ArrayList
seems to work for me - here's a little test:
List list = new ArrayList();
list.add(6);
list.add(7);
list.remove(0);
list.remove(0);
after that the list is empty again.
tested in development mode with gwt 2.0.0
just a guess: make sure, you call the right function
remove is overloaded.
so if you would call:
list.remove(new Integer(0));
then nothing would be removed, because there's no integer
object 0 in the list.

Re: Can't remove 0 index in ArrayList
protected void removeFacultySucceeded() {
display.removeItemFromFacultyList(display.getFacultyListSelectedIndex());
faculties.remove(faculty);
if (!faculties.isEmpty()) {
faculty = faculties.get(display.getFacultyListSelectedIndex());
refreshDisplay();
}
modification = true;
}
I was using the selected index instead of object faculty. While debugging I
confirmed that the first position was 0 ans was an integer... Every other
position was working fine.
I don't understand that bug either, I've worked around by using an object.
Anyway it's not that important, but I wanna know it's just me or it's
something that should be corrected.

Re: Can't remove 0 index in ArrayList
Hello Christian, I looked at the code of ArrayList, but couldn't find anything suspicious. Are you sure your object is at 0? Maybe a null squeezed in at 0, and your object is somewhere later in the list? On which browsers does this happen? On Jan 28, 6:16 pm, Christian Goudreau wrote: > Does anyone had that same problem ?

Can't remove 0 index in ArrayList
Does anyone had that same problem ? Everything works fine when it comes to other indexes, but when I do ArrayList.remove(0), the object is still in here ! But When I try : ArrayList.remove(object), it work again.
