title: Thymeleaf dynamic created form input value
body: <p>I've got form wherefields are generated dynamically, but also I want to put into them values - it's kind a form where user can edit and accept before parsed text. So I'm doing </p>
  
  <pre><code>th:value="${event.value.eventDescription}"
  </code></pre>
  
  <p>and I got only string representing object like</p>
  
  <pre><code>com.myPackage.model.ConferenceEvent@4a78868b
  </code></pre>
  
  <p>instead of real description which is inside this object.</p>
  
  <p>Form:</p>
  
  <pre><code>&lt;form action="#" th:action="@{/approveEvents}" th:object="${conferenceTimetable}" method="post"&gt;
  
      &lt;table&gt;
          &lt;tr&gt;
              &lt;td&gt;&lt;label&gt;Key&lt;/label&gt;&lt;/td&gt;
              &lt;td&gt;&lt;label&gt;EventDate&lt;/label&gt;&lt;/td&gt;
              &lt;td&gt;&lt;label&gt;EventDescription&lt;/label&gt;&lt;/td&gt;
          &lt;/tr&gt;
  
          &lt;tr th:each="event: *{conferenceTimetableMap}"&gt;
              &lt;td&gt;&lt;span th:utext="${event.key}"&gt;Description&lt;/span&gt;&lt;/td&gt;
              &lt;td&gt;&lt;span th:utext="${event.value.eventDate}"&gt;Description&lt;/span&gt;&lt;/td&gt;
              &lt;td&gt;&lt;input type="text" th:field="*{conferenceTimetableMap[__${event.key}__]}" th:value="${event.value.eventDescription}"/&gt;&lt;/td&gt;
          &lt;/tr&gt;
  
          &lt;tr&gt;
              &lt;td&gt;
                  &lt;input type="submit" value="Submit"/&gt;
              &lt;/td&gt;
          &lt;/tr&gt;
      &lt;/table&gt;
  &lt;/form&gt;
