infinite recursion when saving the document with the established tv create_pdf. about pdfresource

[Jako]

What is inside of plugin with the id 17?

[ufabooks]

I haven't found the recursion reason.
by means of the friend have rewritten a plug-in

`<?php

$pdfresourceCorePath = $modx->getOption('pdfresource.core_path', null, $modx->getOption('core_path') . 'components/pdfresource/');
$pdfresource = $modx->getService('pdfresource', 'PDFResource', $pdfresourceCorePath . 'model/pdfresource/', $scriptProperties);

if (!function_exists('checkTvAssigned')) {
function checkTvAssigned(&$pdfresource, &$resource, $tvOptName, $tvDefVal) {
global $modx;
$tplVarTmplTbl = $modx->getTableName('modTemplateVarTemplate');
$tplVarTbl = $modx->getTableName('modTemplateVar');
$pdfTvName = $modx->quote($pdfresource->getOption($tvOptName, null, $tvDefVal));
$tplId = $resource->get('template');

    $assocRes = $modx->query("SELECT `modTemplateVar`.`name`, `modTemplateVarTemplate`.`templateid`
      FROM $tplVarTmplTbl AS `modTemplateVarTemplate`
      LEFT JOIN $tplVarTbl `modTemplateVar`
        ON `modTemplateVarTemplate`.`tmplvarid` = `modTemplateVar`.`id` 
     WHERE (`modTemplateVar`.`name` = $pdfTvName AND `modTemplateVarTemplate`.`templateid` = $tplId );");
    $assigned = $assocRes->fetch(PDO::FETCH_ASSOC);
    return !!$assigned;
}

}

$eventName = $modx->event->name;
