MainController.java

protected void setModelProperty(String propertyName, Object newValue) {
    for (AbstractModel model : registeredModels) {
        try {
            Method method = model.getClass().getMethod("set" + propertyName, new Class[] { newValue.getClass() });
            method.invoke(model, newValue);
        } catch (Exception ex) {
            // TODO Handle exception.
        }
    }
}
