big problems with Grid Listener and KeyDown

[aminef]

BasicallyI have a listener on my grid that allows a delete (on pressing "del" key) and an add (using the "+" key) both of them work great!
I wanted to add to the listener that if the key pressed is a letter, then show a dialog. and the problems start...

1) when the last feature is added, I can't navigate with the arrows on my grid, and can't use the "del" and the "+" keys
2) when I press a key to show the dialog, the be.getValue() (witch is supposed to be the letter typed, is always empty string)
3) and finally when I try to use the startsWith() method, it doesn't work...

Here is my code in order:

the grid listener:

grid.addListener(Events.OnKeyDown, new Listener<GridEvent<PersInfo>>() {
@Override
public void handleEvent(GridEvent<PersInfo> be) {
PersInfo rowData = grid.getSelectionModel().getSelectedItem();
if(be.getKeyCode() == KeyCodes.KEY_DELETE && !rowData.isRemoved()){
//delete
}
if(be.getKeyCode() == 107 && rowData.isRemoved()){// press the + key
//add
}
if(be.getKeyCode() >= 49 || be.getKeyCode() <= 90){
showStartWithDialog(grid.getStore(), (String)be.getValue());
}
}
});

and the other isse is :

listStore.getAt(i).getLName().toLowerCase().startsWith(startWithlname)); returns always FALSE
and i have a Info.Display for the 2 Strings and the getLName is "Adair" and startWithlname is "ad" or "ada" or "a" or even "adair"

1) What last feature are you refering to?

2) be.getValue() does not return you the char that was pressed.

3) I dont know without a testcase.

But for all of your problems, can you please post a fulyl working testcase implementing EntryPoint that demonstrates your problems? Also with version of GWT are you using?

I can't provide a real testing case (quiet big project), but i think this code demonstrate the problem with the screen shot
GXT: 2.2.0

1) the feature is the last if in the handler, once I add this if, the 2 other if and the keyboard navigation on the grid won't work.
2) how to get the value entered from a keycode?
3) here's the exact code:
I am checking if 'lname' starts with 'startString'

int index = listStore.indexOf(grid.getSelectionModel().getSelectedItem());
for(int i = 0; i < listStore.getCount(); i++){
Info.display(startString+" "+lname.toLowerCase(), Boolean.toString(lname.toLowerCase().startsWith(startString)));

if(!startString.equals("") && lname.toLowerCase().startsWith(startString)){
index = i;
}
}
and here's the result of the info.display (http://img704.imageshack.us/f/startswith.jpg/)

You can create a new testcase with just the needed parts. You should not use your current project.

1) and 3) we really need a fully working testcase implmenting EntryPoint for this. You really should take the time, probably 10 minutes, to create one.
2) The browser event has a getter to get the chartcode (you should use KeyPress for this and GWT 2.1)
