Thymleaf switch statement with multiple case

The failure is due to the fact that you don’t have a valid expression in the first case. Specifically,

'COMPLETE','INVALID'

is not a valid expression. I suspect that what you are trying to do is include the div if the status is COMPLETE or INVALID. Unfortunately, I believe you will have to duplicate the markup for those conditions individually. Let me suggest the following markup:

<!-- th:block rather than unneeded div -->
<th:block th:switch="${status.value}">
    <div th:case="'COMPLETE'">
        <!-- print object is not active -->
    </div>
    <div th:case="'INVALID'">
        <!-- print object is not active -->
    </div>
    <div th:case="'NEW'">
        <!-- print object is new and active -->
    </div>
</th:block>

Alternatively you could resort to th:if which might actually work better in this case:

<div th:if="${status.value} eq 'COMPLETE' or ${status.value} eq 'INVALID'">
    <!-- print object is not active -->
</div>
<div th:if="${status.value} eq 'NEW'">
    <!-- print object is new and active -->
</div>

Or even more simply:

<div th:unless="${status.value} eq 'NEW'">
    <!-- print object is not active -->
</div>
<div th:if="${status.value} eq 'NEW'">
    <!-- print object is new and active -->
</div>
