(1) Same problem with the links to parent templated triggers and trigger prototypes in the configuration forms.
<pavels> RESOLVED.
<Toms> CLOSED. see (3)
(2) A couple of related bugs. If we open an inherited graph prototype, follow the link to the parent prototype and save it, we'll be redirected to an empty list. If we do the same with a trigger prototype, we are redirected to a list of trigger prototypes from the original trigger prototypes, not the prototypes from the parent template.
<pavels> RESOLVED.
<Toms> CLOSED. see (3)
It turned out, that there are numerous problems with those links in the frontend.

(3) It is not the best way to pass all ids through URL if they can be retrieved from single id. If trigger id is given it is possible to retrieve hostid from DB.
<richlv> what about triggers that reference multiple hosts ? not sure whether it applies in this case, just curious
<Toms> I think that you can take first or one which are in some way more important in a way in I am not aware of.
<pavels> This will work for items and LLD rules, but will not do for triggers and graphs, because we can navigate to these items from different hosts. I such cases, the navigation form should display the host we came from, not the first one.
<Toms> You can pass id as extra variable when necessary, but if it not set you need to retrieve it from DB.

(4) CPageFilter shouldn't be used in getTriggerFormData() in forms.inc.php
<pavels> RESOLVED.
<Vedmak> CLOSED
(5)
When we select All/All and open some trigger for edit, host bar is not shown. Should be checked for graphs and prototypes too.
<pavels> Same thing for applications.
<pavels> RESOLVED.
<Vedmak> Go to Applications, select All/All, open existing application, host info is missing.
<pavels> It seems to have been broken by your changes in r28971.
- $data['hostid'] = get_request('hostid') ? get_request('hostid') : $data['apphostid'];
+ $data['hostid'] = get_request('hostid', $data['apphostid']);
It is not equivalent, because hostid can also be 0. It this case we should also use the hostid from the application data.
<Vedmak> huh, ok, sorry for that
