Steps to reproduce:

In the following Trigger URL to "Latest data" the macro {HOSTGROUP.ID} is not resolved:

{$ZABBIX_URL}/zabbix.php?action=latest.view&name=deadlock%20detection&show_tags=3&hostids%5B%5D={HOST.ID}&groupids%5B%5D={HOSTGROUP.ID}

This id OK according to the documentation:

https://www.zabbix.com/documentation/current/en/manual/appendix/macros/supported_by_location#host-groups

But the following Trigger URL will show an empty result:

{$ZABBIX_URL}/zabbix.php?action=latest.view&name=open&show_tags=3&hostids%5B%5D={HOST.ID}

Because the hostgroup is preset by a previous lookup and not erased in this case. So the host with the wrong hostgroup is search which leads to no result.

Expected:

• Either resolve hostgroup.id Macro in trigger URL or
• do not inherit hostgroup from previous lookup in Latest Data view. (if hostgroup is not set in url then set hostgroup to NULL)
