[TYPO3-dev] Objects passed explicitely by reference in WorkspaceSelector

[Fabrizio Branca]

Hi there,

is there a reason why objects are passed by reference explicitely in 
class WorkspaceSelector (and in interface backend_toolbarItem)?

public function toggleWorkspacePreview($parameters = array(), TYPO3AJAX 
&$ajaxObj = null) { [...]

Bye,

Fabrizio
