Don't know why but it's working now.

Hi there,I'm trying to implement a counter for a textarea. Something like this is working for mefinal TextArea textArea = new TextArea(); final Label counter = new Label("Number of characters: 0"); ... private void addlistener() { textArea.addKeyUpHandler(new KeyUpHandler() { public void onKeyUp(KeyUpEvent keyUpEvent) { counter.setText(" Number of characters:"+textArea.getText(
). length()); } });In my project the TextArea is enhanced e.g. for displaying validation errors.
public class ValidatableTextarea extends ComplexPanel
private FlowPanel rootPanel;
protected TextArea input;private Label errorLabel;
@UiConstructor
public ValidatableTextarea() {
input = new TextArea();
rootPanel = new FlowPanel();
rootPanel.add(input);
setElement(rootPanel.getElement());
}...
public void setText(String text) {
input.setText(String Text);
}...
public void addKeyUpHandler(KeyUpHandler keyUpHandler) {
input.addKeyUpHandler(keyUpHandler);
}My Presenter is calling ValidatableTextarea.addKeyUpHandler onBind but the keyhandler seems not to be added. The same thing happens when I call ValidatableTextarea.setText My Presenter is a dialog, so when I call those functions in Presenter.open at least ValidatableTextarea.setText is working and the given text is displayed, but there is still no keyUpHandler working.So is there any magic working I don't see? Any event I can listen to be sure that my ValidatableTextarea is ready to accept my keyUpHandler? Or is my given Handler somehow overwritten?Thanks in advance,Marco
