Вопрос про сниппет msProducts в другом сниппете

Пишу аякс фильтр для товаров minishop2 и вот проблеммы, подскажите пожалуйста как решить
1. Если выводить через msProducts внутри pdoPage то отображается пагинация правильно
т.е. так пагинация работает

[[!pdoPage? &element=`msProducts` 
&tpl=`productsgridTpl` 
&limit=`21` 
]] 
<div class="clearfix"></div>
[[!+page.nav]]
</div>

а если через свой сниппет то пагинации нет, на месте [[!+page.nav]] — пустота

[[!pdoPage? &element=`catalogFilter` 
				&tpl=`productsgridTpl` 
				&limit=`3` 
				&parents=`[[*id]]`
				]] 
				<div class="clearfix"></div>
				[[!+page.nav]]

Вот код сниппета catalogFilter

<?php

//Filter Fields Settings
$filter = array();

//Radio, Select & Text Fields Type
if($_GET['code']) {
	$filter[] = 'article='.$_GET['code'];
}

//Two Text Fields From To
if($_GET['price_from']) {
	$filter[] = 'price>='.$_GET['price_from'];
}
if($_GET['price_to']) {
	$filter[] = 'price<='.$_GET['price_to'];
}



//End Settings

//Sort
if($_GET['sortby']) {
	$sortby = $_GET['sortby'];
} else {
	$sortby = 'pagetitle';
}
if($_GET['sortdir']) {
	$sortdir = $_GET['sortdir'];
} else {
	$sortdir = 'asc';
}
//End Sort

//Offset
$offset = 0;
if($_GET['offset']){
	$offset = $_GET['offset'];
}

if($filter) {
	$filter[] = 'isfolder=0';
	$where = $modx->toJSON($filter);

} else {
	$where = '';
}




$params_count = array(
	'parents' => $parents,
	'limit' => 0,
	'tpl' => '@INLINE ,',
	'select' => 'id',
	'includeTVs' => $fields,
	'showHidden' => '1',
	'where' => $where,

	);

$count = $modx->runSnippet('msProducts',$params_count);
$count = count(explode(',',$count))-1;
$modx->setPlaceholder('count',$count);



$params = array(
	'parents' => $parents,
	'limit' => $limit,
	'offset' => $offset,
	'tpl' => $tpl,
	'select' => 'id,pagetitle,introtext,content',
	'includeTVs' => $fields,
	'showHidden' => '1',
	'sortby' => $sortby,
	'sortdir' => $sortdir,
	'where' => $where,
	'showLog'=>'1'
	);

$more = $count - $offset - $limit;
$lim = $more > $limit ? $limit : $more;

$button = '';
if($more > 0){
	$button = '<div class="ajax-filter-count" data-count="'.$count.'"><a href="#" class="ajax-more">Загрузить еще '.$lim.' из '.$more.'</a></div>';
}

return $modx->runSnippet('msProducts',$params).$button;

2. Как объеденить условия выборки для нескольких checkbox
так работает но выдает только по одному параметру

if(!empty($_GET['brands'])) {
	$brs = array();
	$brs = implode(',',$_GET['brands']);
	$filter[] = array('vendor.id:IN' => array($brs));
	
}

Что ему не нравится в этом условии не пойму....? Почему если Added where condition: vendor.id:IN(3,2)
В запросе — AND `vendor`.`id` IN (3)

$newparams = array(
	'sortby' => $sortby,
	'sortdir' => $sortdir,
	'where'=>$where,
	'showLog'=>'1'
	);

return $modx->runSnippet('msProducts',array_merge($scriptProperties,$newparams));
