Thymeleaf dynamic created form input value - forms

Question

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
th:value="${event.value.eventDescription}"
and I got only string representing object like
com.myPackage.model.ConferenceEvent#4a78868b
instead of real description which is inside this object.
Form:
<form action="#" th:action="#{/approveEvents}" th:object="${conferenceTimetable}" method="post">
<table>
<tr>
<td><label>Key</label></td>
<td><label>EventDate</label></td>
<td><label>EventDescription</label></td>
</tr>
<tr th:each="event: *{conferenceTimetableMap}">
<td><span th:utext="${event.key}">Description</span></td>
<td><span th:utext="${event.value.eventDate}">Description</span></td>
<td><input type="text" th:field="*{conferenceTimetableMap[__${event.key}__]}" th:value="${event.value.eventDescription}"/></td>
</tr>
<tr>
<td>
<input type="submit" value="Submit"/>
</td>
</tr>
</table>
</form>

Answer 1

th:field writes the name, value and id of the input it's on. So *{conferenceTimetableMap[__${event.key}__]} is the expressions that evaluates to com.myPackage.model.ConferenceEvent#4a78868b and not ${event.value.eventDescription} (which is never used).
Instead, you should write the complete path to the variable you are submitting in th:field. I can't be sure without know what conferenceTimetableMap contains, but something like this might work:
<input type="text" th:field="*{conferenceTimetableMap[__${event.key}__].eventDescription}" />
