Re: Add a new tag for additional client side JavaScript support

[Carlin Rogers <ca...@gmail.com>]

I can go ahead and do this work, adding a new forTagId attribute to
the <netui:rewriteName> tag so that it rewrites a name using the
scoping in the page rather than the request. Within the implementation
we can call a base class routine,  getIdForTagId() to get the real tag
id to generate rather than going through the URLRewriter. I'll open a
JIRA issue for tracking this enhancement. Thanks again for the help.
