I have a <td> in my jsp which has a <spring:bind> tag.

        <td>
          <spring:bind path="mailListRequest.offSeason">
            <select name="<c:out value="${status.expression}" />" id="<c:out value="${status.expression}" />">
            <option value="0">Select</option>
              <c:forEach var="t" begin="2" step="1" end="5">
                <option value="<c:out value="${t} star"/>" <c:if test="${status.value eq t}"> selected</c:if>><c:out value="${t} star"/>
                </option>
              </c:forEach>
              <option value="boutique hotels">boutique hotels</option>

            </select>
          </spring:bind>
        </td>

"mailListRequest.offSeason" is a string on the server side (Java). The goal here is to iterate in the <c:forEach..> loop variable "t". Therefore the iteration will be 2,3,4,5;and in the <option value..> I've made each iteration return a value with the string/word star in front of it therefore the output would be 2 star, 3 star, 4 star....

The Issue:

The issue is that whenever I choose one of the options in the <c:forEach> loop or the option "botique hotels " I keep getting an error in my JSP:

Error

javax.servlet.jsp.JspTagException: javax.servlet.jsp.JspException: An error occurred while evaluating custom action attribute "test" with value "${status.value eq t}": An exception occured trying to convert String "2 star" to type "java.lang.Long" (null).

Which puzzles me because "mailListRequest.offSeason" is set as a string and the values in my options are String values(I PRESUME). Perhaps it's the <option value="<c:out value="${t} star"/> I'm formatting wrong.
