[TYPO3-calendar] Add custom field to the Frontend Edit

[Max Plettenberg]

Hello!

I tried to add a custom field with the Kickstarter. No problem. The 
field is existing at the backend and it is no problem to save some data. 
Now I tried to get the field ready for the frontend edit... The field is 
visible there, but data won't be saved...

There are two ways on TS but both doesn't work:

First way:
dataWrap = <input type="text" 
name="tx_cal_controller[tx_calfelder_anzahlderpersonen]" 
value="{GP:someGPvar}" />

Second way:
dataWrap = <input type="text" 
name="tx_cal_controller[tx_calfelder_anzahlderpersonen]" value="|" />

Have someone a tip?

Thanks a lot!

Greetz,
Max
