Refresh form once the menu button closed

To refresh the datasource in form once the menu button closed, we need to write the code below at the menubutton > closedOk method.

public void closeOk()
{
    #Task
    FormRun formRun;
    super();

    // Get an instance of the calling form.
    formRun = element.args().caller();

    // If the caller is a form, refresh that form.
    if(formRun)
    {
        formRun.task(#taskF5);
    }
}
