But, it does not work even I changed html-el to html.
In my link, I did pass some fixed values. They are
picked up. Let me explain:
<c:url value="/admin/sortUsers.do" var="ascFirstName">
<c:param name="sortKey" value="firstName" />
<c:param name="orderKey" value="ASC" />
<c:param name="searchFirstName"
value="${searchFirstName}" />
</c:url>
<A href=' <c:out value="${ascFirstName}" /> '></A>
The fixed values "firstName" and "ASC" are picked up
without problem. But the "${searchFirstName}" where
searchFirstName is the property of a text field is not
picked up.
