Revision history for Perl extension Params::CallbackRequest.

1.11  Wed Oct  8 19:27:32 2003
      - Fixed execution of pre and post callbacks so that they execute in the
        order in which they're declared. Thanks to Perl 5.8.1 for rubbing my
        nose in this one!

1.10  Mon Sep  8 21:15:42 2003
      - Code moved over from MasonX::ApacheHandler::WithCallbacks, which is
        deprecated. Differences from that class are as follows.
      - Code from MasonX::ApacheHandler::WithCallbacks has been migrated to
        Params::CallbackRequest.
      - Code from MasonX::CallbackHandler has been migrated to
        Params::Callback.
      - MasonX::CallbackTester has been removed, since it isn't necessary
        in a non-mod_perl environment.
      - Created Params::CallbackRequest::Exceptions to create all of the exception
        classes used by Params::CallbackRequest. These no longer inherit from
        HTML::Mason::Exception, of course, but from Exception::Class::Base.
      - Renamed the "exec_null_cb_values" parameter to "ignore_nulls". It is
        now false by default, and you pass a true value to enable it. Thus the
        semantics are the opposite of "exec_null_cb_values", but the result is
        the same.
      - Renamed the "cb_exception_handler" to "exception_handler", since it's
        now obvious that it applies to callbacks.
      - Changed the request_args() accessor from MasonX::CallbackHandler to
        params() in Params::Callback, to reflect the idea that this is a
        generic parameter-triggered callback architecture.
      - Replaced the ah() accessor, since the callback controller isn't a
        Mason ApacheHandler anymore, with cb_request() in Params::Callback.
      - Replaced the "exec_null_cb_values" parameter from
        MasonX::ApacheHandler::WithCallbaks, which had defaulted to true, with
        "ignore_nulls" in Params::CallbackRequest, which defaults to false.
      - Added notes() to manage per-request notes. Pass a true value to the
        "leave_notes" parameter to new() to allow notes to persist beyond
        calls to request(). In such cases, use clear_notes() to manually clear
        the notes.
