Validation errors wipe out other fields on page

Hi, great plugin.

I found that if you have validation errors on a page, then any changes you’ve made to other fields on the page will revert to their original value.

A quick and simple fix is to test for the current page on the pre-populate filter and only re-load the form if you are on page 1.

function ri_pre_populate_the_form($form) {
    if ($form['isPersistent']) {

		$current_page = GFFormDisplay::get_current_page($form["id"]);
		if ($current_page == 1) {
			$option_key = ri_getFormOptionKeyForGF($form);
			if (get_option($option_key)) {
				$_POST = json_decode(get_option($option_key), true);
			}
		}
    }

    return $form;
}
