ComboBox + javascript.value how to simulate event ?

Vaadin 6 / 7 / 8 Framework UI

Hi all!

I am trying to simulate event that user is writing new value in combobox and then opens the list with mathcing data source values.

TextChangeListener tcl = new TextChangeListener() { public void textChange(TextChangeEvent event) { if (getFocusedChange()) { setFocusedChange(false); if (getId() != null) { if (event.getText().length() > 0) { String actualSeq = event.getText().substring(event.getText().length() - 1, event.getText().length()); JavaScript.getCurrent().execute("document.getElementById('" + getId() + "').firstChild.value='" + actualSeq + "'"); //Not working :( DisComboBox.this.fireEvent(event); } } else { log.log(Level.INFO, "DisComboBox component does not have ID !"); } } } }; With .js i am changing the text field value from old to new. but list is showing empty if i type on keyboard the next symbol from word then list shows, how to simulate keyboard input on ComboBox filter thet after JavaScript execute user will see filtered list?

All code:

            @Override

            }
        });
    }

                setFocusedChange(true);
            }
        }
    });
    this.addListener(tcl);
    this.addBlurListener(new BlurListener() {
        public void blur(BlurEvent event) {
            setFocusedChange(false);
        }
    });
}

TextChangeListener tcl = new TextChangeListener() {
    public void textChange(TextChangeEvent event) {
        if (getFocusedChange()) {
            setFocusedChange(false);
            if (getId() != null) {
                if (event.getText().length() > 0) {
                    String actualSeq = event.getText().substring(event.getText().length() - 1, event.getText().length());
                    JavaScript.getCurrent().execute("document.getElementById('" + getId() + "').firstChild.value='" + actualSeq + "'");
                    MyComboBox.this.fireEvent(event);
                }
            } else {
                log.log(Level.INFO, "MyComboBox component does not have ID !");
            }
        }
    }
};

public Boolean getFocusedChange() {
    return focusedChange;
}

public void setFocusedChange(Boolean focusedChange) {
    this.focusedChange = focusedChange;
}

}
[/code]I tryed markAsDirty and utc but nothing helps …

Thanks for any tip!
