Joomla router.php links displayed correctly but doesnt works joomla 3.7 - joomla

Question

I have a problem with router.php
I cannot found an error in public function parse(&$segments)
The url generated as i want but it doesn't work with sef correct
the parse function gets correctly the view and the id_tsi parameters but id_tsi parameter seems to be not working
Version of joomla 3.7
the url of the component looks like
www.ktopoverit.ru/index.php?option=com_helloworld&view=reestr_si&id_tsi=1
url with switched on sef looks like
www.ktopoverit.ru/poverka/reestr_si/1
$vars looks like
Array (
[view] => reestr_si
[id_tsi] => 1
)
and my router is
class helloworldRouter extends JComponentRouterBase
{
public function build(&$query)
{
$segments = array();
if (isset($query['view']))
{
$segments[] = $query['view'];
unset($query['view']);
}
if (isset($query['id_tsi']))
{
$segments[] = $query['id_tsi'];
unset($query['id_tsi']);
};
return $segments;
}
public function parse(&$segments)
{
$vars = array();
switch($segments[0])
{
case 'reestr_si':
$vars['view'] = 'reestr_si';
$id = explode(':', $segments[0]);
$vars['id_tsi'] = (int) $id[1];
break;
}
return $vars;
}
}

Since your build() method creates the right URLs, it makes sense to take it as the base for some assumptions.
$query contains max. two values, a view (string) and an id (int). One or both of them may be omitted.
So. independent from the actual number of segments, we can just assume that an int represents the id and a string (i.e., everything else) represents the view.
/**
* Parse URL
*
* This method is meant to transform the human readable URL back into
* query parameters. It is only executed when SEF mode is switched on.
*
* #param array &$segments The segments of the URL to parse.
*
* #return array The URL attributes to be used by the application.
*/
public function parse(&$segments)
{
while (!empty($segments))
{
$segment = array_pop($segments);
if (is_numeric($segment))
{
// It's the ID
$vars['id_tsi'] = (int) $segment;
}
else
{
// It's the view
$vars['view'] = $segment;
}
}
return $vars;
}
