Looks neat, but I'd rather have two lines of kludgy code than have to add
two additional libraries to the application. It's pretty basic so far, so
it's probably not worth adding that layer of complexity for this one thing.
Seems like I ought to be able to do this:
<app:HasLogin idMember="<%=loginForm.get("fkMember")%>">
dfdfdf
</app:HasLogin>
but it claims not to know what loginForm is. Argh.
