th:selected a number in a select/option with Thymeleaf doesn't work

I have this code

<div th:class="form-group">
    <td><label class="control-label leftMargin10 rightMargin10" scope="col" th:text="#{insertHours.hhFrom}">Attivita'</label></td>
    <td><select class="form-control" th:field="*{hhFrom}">
        <option th:each="i : ${#numbers.sequence(0, 23)}" th:value="${i}" th:text="${i}" th:selected="${ i==9 } ">Options</option>
    </select>
    </td>
</div>

When I try to add a condition in th:selected it doesn't work.

I have also replaced with this code:

th:attr="${i==9}? selected=selected: '' "

but the result is the same.

The HTML

<select class="form-control" id="hhFrom" name="hhFrom">
    <option value="0" selected="selected">0</option>
    <option value="1">1</option>
    <option value="2">2</option>
    <option value="3">3</option>
    <option value="4">4</option>
    <option value="5">5</option>
    <option value="6">6</option>
    <option value="7">7</option>
    <option value="8">8</option>
    <option value="9">9</option>
    <option value="10">10</option>
    <option value="11">11</option>
    <option value="12">12</option>
    <option value="13">13</option>
    <option value="14">14</option>
    <option value="15">15</option>
    <option value="16">16</option>
    <option value="17">17</option>
    <option value="18">18</option>
    <option value="19">19</option>
    <option value="20">20</option>
    <option value="21">21</option>
    <option value="22">22</option>
    <option value="23">23</option>
</select>

Thanks in advance to answers

You cannot use th:field along with th:selected. If you replace th:field with name=someMeaningfullName the code will work just fine.

Check out this thread on the Thymeleaf forum for more information

Also I found out that if you put <div> tag around option fields, selected="selected" will also work. e.g

<select th:field="*{name}">
    <div>
        <option disabled="true" selected="selected" value="">Select</option>
        <option value="1">first</option>
        <option value="2">second</option>
    </div>
</select>

Another hack that, is pretty simple and works, is to close the select tag: <select ... />

Please note /> at the end of first line:

<select th:field="*{percentage}" />
    <option th:each="i : ${#numbers.sequence(0, 100)}" th:value="${i}" th:text="${i}" th:selected="${i==75}"></option>
</select>

Renders as:

<select id="percentage" name="percentage" />
    <option value="0">0</option>
    <option value="1">1</option>
    ...
    <option value="74">74</option>
    <option value="75" selected="selected">75</option>
    <option value="76">76</option>
    ...
    <option value="100">100</option>
</select>

Both web browser and Thymeleaf will handle this fine.

I used Thymeleaf v.3.0.9.RELEASE
