[TYPO3-english] TCA type-field and required fields

[Victor Livakovsky]

Hi, list.

I'm using a TCE type-feature, when some table contains so called type-field, 
which defines different views of same record at BE and in FE as well. When 
such a type field is changed, whole form is reloaded and record saved, but 
here comes a problem: record is saved on form reload, even, if there are 
some required fields!

Is there any way to tell the core do not allow user switch the type, until 
he has filled required fields? Or disallow core to save record, when type is 
switched?

Thank you in advance.
