Ok I fixed it, with the following changes
-public class ValidatableTextarea extends ComplexPanel
+public class ValidatableTextarea extends FlowPanel
- private FlowPanel rootPanel;
protected TextArea input;
private Label errorLabel;
@UiConstructor
public ValidatableTextarea() {
input = new TextArea();
- rootPanel = new FlowPanel();
- rootPanel.add(input);
+ add(input)
- setElement(rootPanel.getElement());
}
...
public void setText(String text) {
input.setText(String Text);
}
...
public void addKeyUpHandler(KeyUpHandler keyUpHandler) {
input.addKeyUpHandler(keyUpHandler);
}
Don't know why but it's working now.
Cheers
