Codename One - Extend CheckBox to create a SpanToggleCheckBox - codenameone

Question

I need toggle buttons that are multi line, because the text of some of them is long. I tried to extend CheckBox to create a SpanToggleCheckBox, but it doesn't work, because no text is shown. What's wrong in the following code? How can I achive my purpose?
public class SpanToggleCheckBox extends CheckBox {
private TextArea textArea;
/**
* Constructs a toggle checkbox with the given text
*
* #param text to display
*/
public SpanToggleCheckBox(String text) {
textArea = new TextArea(getUIManager().localize(text, text));
textArea.setActAsLabel(true);
textArea.setColumns(textArea.getText().length() + 1);
textArea.setUIID("Label");
textArea.setEditable(false);
textArea.setFocusable(false);
this.setUIID("CheckBox");
super.setToggle(true);
}
/**
* {#inheritDoc}
*/
#Override
public void paint(Graphics g) {
getUIManager().getLookAndFeel().drawTextArea(g, textArea);
}
/**
* {#inheritDoc}
*/
#Override
protected Dimension calcPreferredSize() {
return getUIManager().getLookAndFeel().getTextAreaSize(textArea, true);
}
/**
* Shorthand for creating the SpanToggleCheckBox
*
* #param text the text for the button
* #return a check box
*/
public static SpanToggleCheckBox createToggle(String text) {
SpanToggleCheckBox cb = new SpanToggleCheckBox(text);
return cb;
}
}

I solved this issue with a different approch.
In the code, I replaced with line of code:
Component button = CheckBox.createToggle(label);
with these lines:
CheckBox myBtn = CheckBox.createToggle("text");
Container container = new Container(BoxLayout.y());
container.setLeadComponent(myBtn);
SpanLabel multiLineText = new SpanLabel(label);
container.add(multiLineText);
In this way, I got a Container that acts like a Toggle Button and that contains a SpanLabel with the multiline text.
