Fixes issues with GridStata_Data being returned from various states when value types are necessary.
Pruning of dead code from GridFieldAddExistingAutocompleter
Documentation for GridState
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.
Avoid PHPUnit throwing "test didn't run any assertions"
notices in PHP. If nothing else, it keeps test output
looking less broken by default, making it more likely
that actual errors do get noticed.
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.
API CHANGE: Simplified state handling so that it's just a key store. Affectors are replaced with GridField_ActionProviders. API CHANGE: Removed GridField state manipulation actions instead opting for GridField_ActionProvider actions.
API CHANGE: Removed support for modifiers that add "body" rows, instead having core support for generating the body rows hardcoded into the GridField.
API CHANGE: Allow modification of columns across the whole GridField with the GridField_ColumnProvider interface.
API CHANGE: Renamed GridField_AlterAction to GridField_Action, and added actionName/args parameters, since it can be used for all actions (including batch actions and row actions)
API CHANGE: Removed GridFieldRow class.
