All,
Further investigation revealed, that 'out dict'  variable, returned from
CuteEditor.CEU.SplitEditorSetting(context,out culture,out policy,out dict) call
in public CuteEditorSqlFileStorageProvider(HttpContext context):base(context) constructor is empty.
It happened, because there is no 'setting' parameter in Request, passed in context...

 

Any comments/suggestions would be appreciated
