Hi,

I changed my Nagvis General configuration today, by setting the header template (in Overview Page).
I replaced "default" by "on-demand-filter".

Now, each time I launch Nagvis, I got this :

Error: (0) Undefined index: backend_id (/srv/eyesofnetwork/nagvis-1.8.5/share/frontend/nagvis-js/classes/NagVisHeaderMenu.php:280)

#0 /srv/eyesofnetwork/nagvis-1.8.5/share/frontend/nagvis-js/classes/NagVisHeaderMenu.php(280): nagvisExceptionErrorHandler(8, 'Undefined index...', '/srv/eyesofnetw...', 280, Array)
#1 /srv/eyesofnetwork/nagvis-1.8.5/share/frontend/nagvis-js/classes/NagVisHeaderMenu.php(76): NagVisHeaderMenu->getMacros()
#2 /srv/eyesofnetwork/nagvis-1.8.5/share/frontend/nagvis-js/classes/FrontendModOverview.php(78): NagVisHeaderMenu->__toString()
#3 /srv/eyesofnetwork/nagvis-1.8.5/share/frontend/nagvis-js/classes/FrontendModOverview.php(55): FrontendModOverview->showViewDialog()
#4 /srv/eyesofnetwork/nagvis-1.8.5/share/server/core/functions/index.php(120): FrontendModOverview->handleAction()
#5 /srv/eyesofnetwork/nagvis-1.8.5/share/frontend/nagvis-js/index.php(53): require('/srv/eyesofnetw...')
#6 {main}

If someone could help... Nagvis is out of order, it's quite a disaster...

Thanks...

Hi,

I finallly found a way to solve the problem. It sounds a little bit as a makeshift job, but it helped to fix the issue...

I modified the code of the /srv/eyesofnetwork/nagvis-1.8.5/share/frontend/nagvis-js/classes/NagVisHeaderMenu.php file, at line 278, in order to not enter in the beneath block code, where the error occurs at line 280.

I just changed the test condition if ($this->templateName == 'on-demand-filter') by if ($this->templateName == 'on-demand-filter1') (for instance...).

In that way, the line 280 was not executed. Nagvis overview became available anew...
Just have to click on an existing map. Thereafter the menu was available and I changed back the headertemplate to "default"...

Glad you got it fixed.

Are we okay to close this thread?
