Select option not selected in the c:choose in boot

问题:

I want to select value selected if condition match c:choose options. I have used bellow hidden input value to compare in c:when test=

<input type="hidden" class="form-control" id="dialog_uomid" name="dialog_uomid"  /> 

I have used bellow code in dropdown.

            <select class="form-control" id="uomid" name="uomid"    path="uomid">
                        <option data-tokens="ketchup mustard" value="">--Select Options--</option>
                            <c:forEach var="item" items="${uomList}">

                               <c:choose>
                                    <c:when test="${item.softcode == '${#dialog_uomid}'}">

                                        <option selected="selected" data-tokens="ketchup mustard"
                                                                        value="${item.softcode}">${item.codDes}</option>
                                    </c:when>
                                <c:otherwise>
                                  <option data-tokens="ketchup mustard"
                                                                    value="${item.softcode}">${item.codDes}</option>
                        </c:otherwise>
                    </c:choose>
                </c:forEach>
            </select> 

Comparing bellow code is not working..

<c:when test="${item.softcode == '${#dialog_uomid}'}"

Can you help me to solve the problem dialog_uomid to item.softcode?
