[TYPO3-mvc] Extbase: No way to store NULL / leave form fields empty?

[Gianluca Strafella]

Hi Till,
I would try this (all steps in sequence):
1) you can try to change TCA configuration remove both "default" and "eval" properties.
2)  check column "mw" on database table. Are you sure that field is nullable and it haven't default val ? 
3) Check also file your_ext/ext_tables.sql. It should be coherent with database column.
3) Unistall extention and re-install extention by Extention Manager (this will remove additional extbase framework cache)

I hope this helps you.
Gianluca
