in the following code snippet:
<PRE>
<INPUT TYPE="checkbox" 
        <c:if test="${serviceType.selected}" >
                   checked
        </c:if>
   >${serviceType.techDesc} <br>
</PRE>
the closing tag of the c:if (NOT of the INPUT) is not recognised by the editor (syntax coloring) and is
flagged as an error ('unpaired end tag')
However, if saved and run under (eg) SJAS the resulting HTML is rendered correctly (with check boxes appropriately checked)

A few lines above, it looks as if in

<c:if test="${! empty param.message}" >

the closing tag is not recognised (syntax coloring is not correct) BUT no error is flagged.
