Thanks for the pointer. I don't quite follow why useBean is necessary in
your example.
I wrote my own tag for this. It's very simple - it's just a body tag that
does: pageContext.setAttribute(id, getBodyContent().getString()). It's
useful in those cases where you want to nest tags but can't. Instead of:
<x:tag1 attr1='<x:tag2/>'/>
you do:
<y:eval id='anId'><x:tag2/></y:eval>
<x:tag1 attr1='<%= (String) pageContext.findAttribute("anId") %>'/>
Providing a TEI class would shorten this a lot, but I haven't gotten around
to it yet...
