I want to concatenate 2 vars into a string in EL but since one is a Long, EL
can't do it, and throws a NumberFormatException because it wants them both to be
Longs so it can do arithmetic addition instead.
You could set a string variable this way:
<c:set var="myStringVariable"><c:out value="${category.id}"/></c:set>
That's not quite the minimalist approach I was thinking of, but it is one
approach.
Another approach which saves that whole line is to write another taglib function
and use it like this:
<a href="${pc:url(pc:concat('/category/edit.html?id=', category.id))}">
where pc: is my taglibrary, but I'd like to avoid a proliferation of these
taglib functions in my app.
