Default Value in Checkbox Form

I am trying to get a checkbox to come up initially checked in a Form (v6.8.9). My Form looks something like this:


public class NewLinePlanItem extends Window {
	private Form lp;
	...

	public NewLinePlanItem() {
		lp = new Form();
		lp.setFormFieldFactory( new NewLinePlanFieldFactory() );

NewLinePlanFieldFactory looks like this:


public class NewLinePlanFieldFactory implements FormFieldFactory {
	...

	@Override
	public Field createField( Item item, Object propertyId, Component uiContext ) {
		String pid = (String) propertyId;

		if ( pid.equals( LinePlanItem.ACTIVE ) ) {
			return new CheckBox( "Active", true );

Is there something else I need to do to get the Active checkbox to default to checked?
