I'll get onto raising a bug report, but this is just to note that there is an apparent bug in this class in both 5.8 and 5.9, here is the fix:
@Override
public Field getPropertyField(FormProperty formProperty) {
CheckBox checkBox = new CheckBox(getPropertyLabel(formProperty));
checkBox.setRequired(formProperty.isRequired());
checkBox.setEnabled(formProperty.isWritable());
if (formProperty.getValue() != null) {
Boolean value = new Boolean(Boolean.parseBoolean(formProperty.getValue())); // bug fix
checkBox.setValue(value);
}
return checkBox;
}
This is the Exception fixed:
Caused by: java.lang.IllegalArgumentException: CheckBox only accepts Boolean values
