OrderBy

How can use the OrderBy ODATA function in a filter() request?

[DaveyGiesen]

Ah fixed it. For other users. You need to create a array in the in the filter() request.
Example:
$lines->filter('OrderID eq guid\'' . $salesorder['OrderID'] .'\'', '', '', array('$orderby' => 'LineNumber'));
One note. You need to change this in Findable.php at the filter function.
array_merge($system_query_options, $request); to
array_merge($request, $system_query_options);
OrderBy needs to be after the request and not before.
