I confirm this.

$elActions is boolean in 4.0 while it is an array in 3.x, thus why we get this Invalid argument

Maybe we need to do

		// Iterate over the asset actions and add to the actions.
		if ($elActions)
		{
			foreach ($elActions as $item)
			{
				$actions[] = $item->name;
			}
		}

@laoneo ?

Since$elActions is a boolean, then there is no purpose in looping through it as if it is an array.
