Using JSTL to check for empty attribute

[ha...@informatiefabriek.nl]

Hi all,

I used to check for empty attributes with the:

<logic:present name="variableToCheckFor">

syntax. I would like to do the same thing using JSTL but I'm stuck here. 
Can you guys help?

I use:

<c:choose>
        <c:when test="${corrections == null} ">
                <!-- display some html -->
        </c:when>
        <c:otherwise>
                <!-- display some other html -->
        </c:otherwise>
</c:choose>

Although when I open the page the variable corrections is not null, it 
still displays the content in the 'otherwise' section.

'corrections' by the way is a Collection.

Can you help?

Thanks,
