Fixing follow
 - The order of calling: first should be set the filter, after
   that can be set the current filter
 - change the function from "setCurrentFilter" to "setCurrentItem"
   When you set the filter over "setCurrentFilter" you need the full
   search string "extention|description" e.g. "*.docx|Microsoft Word.."
-  Not need the escape of slash (with that can not find
   "Microsoft Word 2007/2010 XML (.docx))"
