Hi,

I've just updated my SS from 3.1 to 3.4 version and I have one small issue - sort function doesn't work anymore but not completelty.

Here is bit of my code:

public function RelatedDownloads() {

	$Related = new ArrayList;	
	
	// take two items from download section
	$DownloadPage = DownloadPage::get()->sort('RAND()')->limit(2);
	
	// take one element from resource section from specific category
	$RelatedResources = Resource::get();
	$RelatedResources = $RelatedResources->leftJoin('Resource_Categories', "Resource.ID = Resource_Categories.ResourceID")->filter('Resource_Categories.ResourceCategoryID', array('5','6'))->sort('RAND()')->limit(1);
	
	// merge downloads and resource together
	foreach( $DownloadPage as $obj ) $Related->push( $obj );
	foreach( $RelatedResources as $obj ) $Related->push( $obj );
	
	// reorder them randomly
	$Related = $Related->sort('_SortColumn0', 'RAND()');

	return $Related;	
	
}

That was working fine on 3.1 now I'm getting error:

[22-Jul-2016 14:41:05] Error at \framework\model\ArrayList.php line 378: Uncaught InvalidArgumentException: Invalid sort() direction (http://www.domain.com/documents/?download=10995)

However when I change RAND() to ASC or DESC it works fine...

Any clues?

Many thanks, Alessia.
