Flexform: Minitems > 0 within section prevents from saving
When writing a flexform and providing a section you can not define a group/select field with minitens=1 option. Even if no element is created in the section TCEforms gives you a validation error (please fill in all fields...). But as long as no element is created in the section the minitems should not have any effect.
I dont know when this first occured, it definitly exists in 7.3
