add a method deleteLastPopup which delete the last popup of results showed.

we can found (in my case i can found for the classname) and delete , then
the new result will be show

Hello, I know this is an old post, but it helped me and I was able to
improve so I thought I'd share my findings.
Jorge you're fix for the placement does work, but it opens up a new issue
with the multiple popups. That issue I wasn't able to solve, because the
SuggestBox is trying to do this cleanup itself and we're fighting each
other, so I had to backtrack a bit and find a new fix for the placement
issue.
Creating a new suggest box is what's causing the multiple popups to appear.
Just by taking this part out, it fixes the multiple popups.
Now is the issue of placement.
To handle this I simply created a new suggest box each time the edit method
is called, regardless if one exists in the map.
This way the suggest box always has a TextBox so it can place it's menus
correctly, and we never create more than one SuggestBox so we never get
duplicate menu's.
My edit method looks like below.
protected void edit(Context context, Element parent, String value) {
setValue(context, parent, value);
InputElement input = getInputElement(parent);
input.focus();
input.select();
// Always create a new SuggestBox so it opens at the correct
place.
// Never create more than one SuggestBox, otherwise you will
end up with multiple pop up menus.
TextBox textBox = new MyTextBox(input);
parent.replaceChild(input,
textBox.getElement()).getOwnerDocument();
SuggestBox suggestBox = getNewSuggestBox(context,
getSuggestOracle(), textBox);
suggestBoxes.put(getKeyFromContext(context), suggestBox);
}
In addition one big thing I had to do was handling the commits.
There is a bit of a conflict here, because a commit will be performed when
selecting a suggestion (blur). So to handle this part I save the commit
data, let the cell commit as normal in onBrowserEvent, then on the
SuggestBox select event I call the commit again with the saved data and the
selected value. Below is my SuggestBox handler which performs this.
suggestBox.addSelectionHandler(new
SelectionHandler<Suggestion>() {
@Override
public void onSelection(SelectionEvent<Suggestion>
event) {
CommitParameters cp =
SuggestCell.this.commitParameters.get(getKeyFromContext(context));
// A commit is always performed on blur,
// the selected text was inserted, but then
lost by the blur commit (this is needed in case a selection isn't made).
// Re-insert it so the commit can be
performed using the selection text.
InputElement input =
getInputElement(cp.parent);
input.setValue(event.getSelectedItem().getReplacementString());
SuggestCell.this.commit(cp.context,
cp.parent, cp.viewData, cp.valueUpdater, cp.event);
}
});
