Spring Error during execution of processor

Question

Full error is:

Error during execution of processor 'org.thymeleaf.spring4.processor.attr.SpringInputGeneralFieldAttrProcessor' (search:12)

My search.html page displays when I have:

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
    <!--<meta charset="UTF-8">-->
    <title>Search Users</title>
</head>
<body>

<h3>Search Users</h3>
<form th:action="@{/user/search}" th:object="${searchCriteria}" method="post">
<p>First Name: <input type="text" value="*{firstname}"/></p>
<p>Last Name: <input type="text" value="${searchCritera.lastname}"/></p>
    <br/>
    <input type="submit" value="search"/>
</form>
</body>
</html>

But I then changed value to th:field for *{firstname} and ${searchCritera.lastname} as below:

<form th:action="@{/user/search}" th:object="${searchCriteria}" method="post">
<p>First Name: <input type="text" th:field="*{firstname}"/></p>
<p>Last Name: <input type="text" th:field="${searchCritera.lastname}"/></p>
    <br/>
    <input type="submit" value="Search"/>
</form>

Now I get the error above and can't seem to fix it. I tried th:value but it throws another error:

Exception evaluating SpringEL expression: "searchCritera.lastname" (search:12)

In general, when you're using dollar signs, use th::

<input type="text" th:value="${searchCriteria.lastname}"/>

And spell the variable name correctly.

Also include name= or th:field= as appropriate (or instead, depending on what you're trying to accomplish).
