Thymeleaf th:each noting include din template

I have a Thymeleaf fragment which contains some status text and an th:each which does not appear in the output. I have been able to include the model value in the output its a list<list> and is displayed as [[ 8,9...][..]...]] all the values are correct. I have run with logging.level.org.thymeleaf=trace to get the logs, but it appears that nothing is wrong to me.

The fragment is:

   <span th:fragment="view">
    <div class="centered">
        <h1 th:text="${sudoku_description}"></h1>
        <h1 th:text="${sudoku}"></h1>
        <div class="centered" >
            <th:block th:each="puzzledata, rowStat : ${row}">
                <div class="sudoku-row" >
                    <th:block th:each="row, colStat : ${cell}">
                        <div class="sudoku-cell" row="rowStat.index" col="colStat.index" th:text="${cell}"></div>
                    </th:block>
                </div>
            </th:block>
        </div>
       </div>
    </span>

The 2 tag are present and correct but the following <div class="centered" > on inspection is empty. I have tried changing the th:block to a div made no difference. Running from Intelij no exceptions or errors in the console.

Everyday development day provides evidence of just how stupid one can be.

The problem was the values in the th.each wrong way round!

This works:

<th:block th:each="row, rowStat : ${puzzledata}">

This does not:

 <th:block th:each="puzzledata, rowStat : ${row}">
