ComboBoxItem not clearing empty display value

[ellisd5]

Thanks for the reply, will implement what you have suggested

Use hint+showHintInField instead. Those emptyDisplayValue APIs really apply more to SelectItem and other FormItems that don't have an interactive text input area.

Hi all,

I have a ComboBoxItem with the empty display set to "-- Please Select --" However when I click on the box to filter the results the empty display values is set as the filter and you have to manually clear the value so that you can start typing allowing you to utilize the filtering.

This is my work around for the issue...

final ComboBoxItem selectItem = (ComboBoxItem) formItem;
selectItem.setAllowEmptyValue(true);
selectItem.setEmptyDisplayValue("-- Please Select --");

selectItem.addFocusHandler(new FocusHandler() {
    @Override
    public void onFocus(FocusEvent focusEvent) {
        if (selectItem.getValue() == null) {
            selectItem.setAttribute(ORIGINAL_EMPTY_DISPLAY_VALUE, selectItem.getEmptyDisplayValue());
            selectItem.setEmptyDisplayValue("");
            selectItem.redraw();
            selectItem.showPicker();
        }
    }
});

selectItem.addBlurHandler(new BlurHandler() {
    @Override
    public void onBlur(BlurEvent blurEvent) {
        selectItem.setEmptyDisplayValue(selectItem.getAttribute(ORIGINAL_EMPTY_DISPLAY_VALUE));
        selectItem.redraw();
    }
});

Is there a better way to implement this?
Thanks,
Dale
