Your problem isn't OGNL in parameters, you are using EL in your
examples. By default, EL expressions are disabled, but you could easily
switch your expressions to OGNL. I'm guessing that if you use '%'
instead of '$' it will probably work. If your action has a getItem(),
and the returned object has a getId(), then %{item.id} should work, and
if the %{ and } may not even be necessary.
${ triggers EL expression parsing, but this is done by the app server,
if the TLD specifies that the attribute accepts EL (which struts tags do
not by default, unless you change the TLD which isn't advisable).
%{ forces OGNL expression. OGNL expression evaluation happens within the
tag's code, so the app server knows nothing about this step. Thus, the
TLD file's directives have nothing to do with this parsing. Many of the
Struts 2 tag's attributes will attempt to parse parameters as OGNL by
default, but %{ will force parsing.
