Java Question

Thymeleaf - Spring . Accessing a object property inside another object

I have this classes

public class Guardian {

public Guardian() {

private Long id;

private String name;

public class AlarmNotification {

private Long id;

private Guardian guardian;

and in my Thymeleaf template

<td class="col_name" th:text="${}"></td>

But I got this Exception

org.springframework.expression.spel.SpelEvaluationException: EL1007E: Property or field 'name' cannot be found on null

Answer Source

guardian is null. Add ternary operator for processing this case :

<td class="col_name" th:text="${ == null ? '' :}"/>
