multimodelform extension doesn't validate new added fields.

Hello,

I have used multimodelform extension.I have followed all the steps which are written in document.

it works fine. but i have faced issue in validation. it validate only first record on click of submit. when i add second fields onclick of add new button and if i doesn’t add any values in it then it doesn’t validated. successfully inserted record which is wrong. it must be validate second record if it doesn’t filled.

Any solution??

Thanks in advance.
