Deprecated getDocumentSets() method called in CMS

[AndrewHaine]

DMS Version 2.2.0

When visiting a page with document sets in the CMS the deprecation notice is shown - looks like this is a result of the way ViewableData automatically prepends 'get' when retrieving properties:

// ViewableData.php line 119
if (strtolower($property) !== 'field' && $this->hasMethod($method = "get$property"))

Thanks for reporting @AndrewHaine In order for a deprecation notice to be displayed, your site must be configured into dev mode, which is generally unadvisable for production sites.

The method was deprecated recently (in https://github.com/silverstripe/silverstripe-dms/pull/206) to fix a 500 error related to the magic lookup you're referring to in ViewableData (infinite recursion).

If you'd like to disable deprecation notices in your development environment you can choose to either:

• for this project: Deprecation::set_enabled(false); (e.g. in mysite/_config.php)
• for all projects: define('SS_DEPRECATION_ENABLED', false); in your _ss_environment.php file.
