New Post: Error PHPExcel/Writer/.php

Sorry, didn't investigated it enough by myself. And my problem is not related to this thread. The problem was in composer. In my export service I have const like

const BORDER_STYLE = \PHPExcel_Style_Border::BORDER_HAIR;

which I use several times in service, and on Zend initialization, Zend is trying to pass service locator to my service. PHPOffice is not installed, hence, service cannot be initialized, and that's why I see this error. I've re-updated all my packages and all works fine, but I really appreciate your quick response. Thanks
