+=item error_step (method)
+
+Defaults to "__error". The name of a step to run should a dying error
+be caught by the default handle_error method. See the handle_error method.
+
=item exit_nav_loop (method)
This method should not normally used but there is no problem with
See the section on FINDING TEMPLATES for further discussion.
-=item first_step (method)
-
-Returns the first step of the path. Note that first_step may not be the same
-thing as default_step if the path was overridden.
-
-=item form (method)
-
-Returns a hashref of the items passed to the CGI. Returns
-$self->{form} which defaults to CGI::Ex::get_form.
-
-=item handle_error (method)
-
-If anything dies during execution, handle_error will be called with
-the error that had happened. Default action is to die with that error.
-
-=item history (method)
-
-Returns an arrayref which contains trace history of which hooks of
-which steps were ran. Useful for seeing what happened. In general -
-each line of the history will show the current step, the hook
-requested, and which hook was actually called.
-
-The dump_history method shows a short condensed version of this
-history which makes it easier to see what path was followed.
-
-In general, the arrayref is free for anything to push onto which will
-help in tracking other occurrences in the program as well.
-
-=item init (method)
-
-Called by the default new method. Allows for any object
-initilizations that may need to take place. Default action does
-nothing.
-
=item fill_args (hook)
Returns a hashref of args that will be passed to the CGI::Ex::Fill::fill.
This hook is only necessary if the hash_validation hook has not been
overridden.
-
+5B
This method an also return a hashref containing the validation - but
then you may have wanted to override the hash_validation hook.
See the run_hook method and the morph method for more details.
+=item first_step (method)
+
+Returns the first step of the path. Note that first_step may not be the same
+thing as default_step if the path was overridden.
+
=item forbidden_step (method)
Defaults to "__forbidden". The name of a step to run should the current
step name be invalid, or if a step found by the default path method
is invalid. See the path method.
+=item form (method)
+
+Returns a hashref of the items passed to the CGI. Returns
+$self->{form} which defaults to CGI::Ex::get_form.
+
=item form_name (hook)
Return the name of the form to attach the js validation to. Used by
be done via the auth_args hash. See the auth_args method and
CGI::Ex::Auth perldoc for more information.
+=item handle_error (method)
+
+If anything dies during execution, handle_error will be called with
+the error that had happened. Default action is to try running the
+step returned by the error_step method.
+
=item hash_base (hook)
A hash of base items to be merged with hash_form - such as pulldown
returned or if the get_validation fails, an empty hash will be returned.
Validation is implemented by ->vob which loads a CGI::Ex::Validate object.
+=item history (method)
+
+Returns an arrayref which contains trace history of which hooks of
+which steps were ran. Useful for seeing what happened. In general -
+each line of the history will show the current step, the hook
+requested, and which hook was actually called.
+
+The dump_history method shows a short condensed version of this
+history which makes it easier to see what path was followed.
+
+In general, the arrayref is free for anything to push onto which will
+help in tracking other occurrences in the program as well.
+
=item info_complete (hook)
Calls the ready_validate hook to see if data is ready to validate. If
sure the data is ready and valid. Will not be run unless
prepare returns true (default).
+=item init (method)
+
+Called by the default new method. Allows for any object
+initilizations that may need to take place. Default action does
+nothing.
+
=item insert_path (method)
Arguments are the steps to insert. Can be called any time. Inserts
