AIM: I have to make one fields mandatory in contribution mode, so that it can't be null.
When we launch contribution mode we get few fields in Element Tab and few in Meta data Tab. I have to make one field mandatory under Metadata Tab. I have made that field mandatory in content Server and it works fine only once User visits "Metadata Tab". If user doesn't click "MetaData Tab" and remains in element Tab and saves the changes then we don't get mandatory message.
can we do something to check the null condition in Element Tab for metadata field.
