>          Components: Engine

> Result expected: <c:if test="${userForm.id != null}">.
> As you can see, it's a widely use JSTL core tag.
> The precondition is: #set ($formName = "user")
> I tried 4 ways:
> one:
> 	<c:if test="${${formName}.id != null}">
> two:
> 	#set ($D = '$')
> 	<c:if test="$D{${formName}Form.id != null}">
> three: use the EscapeTool
> 	<c:if test="${escape.d}{${formName}Form.id != null}">
> four: !@#(^*%%(*^....
> 	#set ($D = '$')
> 	#set ($LEFT_B = '{')
> 	#set ($RIGHT_B = '}')
> 	<c:if test="$D{${formName}Form.id != null}">
> But all 3 ways failed, with the same error:
> org.apache.velocity.runtime.parser.ParseException: Encountered " != null} , Was
> expecting one of:
>     "}" ...
>     <DOT> ...
>     
> currently all I can do is NOT USE the JSTL, replaced it with the ugly java code:
> <%if (((User)request.getParameter("userForm")).getId() != null) %> ...
> any suggest?
> Thanks.
