RequestHandler#handleAction now exists. It takes the request, and
the action to call on itself. All calls from handleRequest to call an action
will go through this method
Controller#handleAction has had it's signature changed to
match new RequestHandler#handleAction
RequestHandler#findAction has been added, which extracts the
"match URL to rules to find action" portion of RequestHandler#handleRequest
into a separate, overrideable function
GridField#handleAction has beeen renamed to handleAlterAction and
CMSBatchActionHandler#handleAction has been renamed to handleBatchAction to
avoid name clash with new RequestHandler#handleAction
Reason for change: The exact behaviour of request handling depended heavily
on whether you inherited from RequestHandler or Controller, and whether the
rule extracted it's action directly (like "foo/$ID" => 'foo') or dynamically
(like "$Action/$ID" => "handleAction"). This cleans up behaviour so
all calls follow the same path through handleRequest and handleAction, and
the additional behaviour that Controller adds is clear.
This hook is useful so that you can add additional fields / actions in a gridfield form that are not available in other settings (e.g. additional actions: previous / next / save and publish / unpublish / etc
GridField uses createTag() which is marked for deprecation, rather
than have it used as the cornerstone of generating FormField templates,
use it as a helper in case fields generate HTML tags from PHP.
The existence of .ss-tabset triggers JS which applies $.tabs(),
and in turn interprets the first available link as the tab navigation.
jQuery UI subsequently tries to ajax-load this link, which is not
desired. Instead, $.tabs() should *only* be applied to a container
DOM element with .cms-tabset applied.
The entire framework repo (with the exception of system-generated files) has been amended to respect the 120c line-length limit. This is in preparation for the enforcement of this rule with PHP_CodeSniffer.
Fixes the handleAction function of GridFieldDeleteAction which wasn't differentiating between a 'deleterecord' action and an 'unlinkrelation' action.
Fixes http://open.silverstripe.org/ticket/7801
Wasn't refreshing after ajax save operations on existing
content, as the URL didn't change, and hence the CMS
didn't reload the view. Return the view directly instead,
unless we're dealing with new records (= changed URL).
The classnames on the add-new button and breadcrumbs were not
translated due to the use of singular_name() instead of
i18n-singular_name() in GridFieldAddNewButton and GridFieldDetailForm.
