The problem is slightly different then just being a null. The problem is that
shop is null, so user.getShop().getShoCode() throws an exception. So the
problem is that one step removed from the value to be displayed is a null.
You can deal with this more easily by using the ?. operator.
${user.shop?.shoCode}
?. will stop if shop is null.
