[TYPO3-project-seminars] CSV-Export - missing content

[Andrea Frehse]

Hi,
I`ve got following problem with the CSV-Export of seminar-data:

All is fine, but two fields (begin_date , end_date) are exported without 
content although there is content  in the database and its shown in FE 
and BE. Ofcourse this both fields are listed in the TS-Setup, original 
without line-brake (please don´t wonder, there are some additional 
fields like "duration" - the customer needed a textarea)

fieldsFromEventsForCsv = 
title,subtitle,categories,teaser,description,notes,additional_information,targets,methods,practicals,exam,required_knowledge,responsible,begin_date,end_date,duration,deadline_registration,details_page,place,room,speaker,price_regular,cost_info,organizers,attendees_min,attendees_max,target_group,cancelled,notes,attached_files

What is wrong/missing?
Thanks for a hint.
best regards
Andrea Frehse
