Attribute th:field will replace attributes value, id and name in your input tag.

Instead, use plain th:id, th:value and th:name without using th:field. Then you will get what you wanted.

Then it will look like:

<input type="text" th:value="${product.name}" th:name="name" th:id="name" th:errorclass="fieldError"/>

Answer 2

Using th:field or value, id and name is ok. if you user th:field, you can write this：

<input type="text" th:field="${product.name}" th:value="${product.name}" "th:errorclass="fieldError"/>

Answer 3

Because Attribute th:field is Combination of both th:name and th:value So, either use this:

<input type="text" th:value="${product.name}" th:name="name" th:errorclass="fieldError"/>

Or this:

<input type="text" th:field="*{name}" "th:errorclass="fieldError"/>
