Filter Operator "Is between" field titles missing

here is a screen what i means.

Its a exposed filter of node:post date and set to "is between"

here is the code, it seams they shouldn't be printed, anyone know why?

<?php
      $form['value']['min'] = array(
        '#type' => 'textfield',
        '#title' => empty($form_state['exposed']) ? t('Min') : '',
        '#size' => 30,
        '#default_value' => $this->value['min'],
      );
      $form['value']['max'] = array(
        '#type' => 'textfield',
        '#title' => empty($form_state['exposed']) ? t('And max') : t('And'),
        '#size' => 30,
        '#default_value' => $this->value['max'],
      );
?>

I probably did that due to the difficulty in figuring out how the titles should actually look with just a single label.

ok this makes sense, but displaying nothing is worse then displaying just like the default way. "min" "and max"

You should fix this, dereine. :)

It's a bit problematic because this logic is currently not part of the filter handler, but by the theme.inc preprocess function.
