Exposed filter group doesn't work

I was having the same problem, none of the grouped filters would work. You can add them in the view admin but they all resulted in an error when trying to actually filter by them in the form.

zviryatko's patch didn't work for me. Not sure if he's on a different version but the code looked different.

I'm on version 1.0.1.

Attached a patch that resolved the issue for me on our version. I did similar thing as zviryatko and just added this check at the top of DateBase::acceptExposedInput()

    if ($this->isAGroup()) {
      return parent::acceptExposedInput($input);
    }

thanks @ceithamer728, actually I've tried to include the case to use default parent method when grouping is enabled, but it looks like not all cases. Can you give more context what grouping filters you have, or upload screenshot of views filter configuration, will try to add some tests that covers both.
