Hi VIVO-Team,--
after installing VIVO1.9.2 via github, I got an error on nearly all pages.:
Caused by:
FreeMarker template error:The following has evaluated to null or missing:==> vClassGroups [in template "lib-home-page.ftl" at line 118, column 37]Can you give me an hint?
There was a similar problem with an explanation, but I don't know what to do about it.: https://groups.google.com/forum/?_escaped_fragment_=topic/vivo-tech/iENhkq12HxM#!topic/vivo-tech/iENhkq12Hx
Thanks in advance for your help.

Hi Wolf,
Graham may have further suggestions but I looked this over a little and had some questions that may be useful to answer as we try to track down what is leading to this error.
https://github.com/vivo-project/VIVO/blob/develop/webapp/src/main/webapp/templates/freemarker/lib/lib-home-page.ftl#L118 is the line throwing the error. This page is included in page-home.ftl. The vclassgroup variable is expected to be available when this macro is called, which leads me to believe that perhaps the system is not seeing the vclassgroups that it normally expects to (as it loads with some classgroups defined).
If you could do one of the following: check the class group page using the link on the site admin page or query the system (either using the site admin sparql query page or the sparql query api) to check if any class groups exist (i.e. SELECT ?classgroup where ?classgroup http://www.w3.org/1999/02/22-rdf-syntax-ns#type http://vitro.mannlib.cornell.edu/ns/vitro/0.7#ClassGroup .)
If you do see classgroups, we’ll have to review why the system doesn’t populate that variable. If you don’t, we’ll have to review why the system has not loaded them (this file defines them https://github.com/vivo-project/VIVO/blob/develop/home/src/main/resources/rdf/applicationMetadata/firsttime/classgroups.rdf and should be loaded into the system the first time you deploy).
Hope this helps!

Hi Daniel,
I have a feeling that null vClassGroups is a misleading symptom of the same underlying problem. I’ve seen this happen in the past when VIVO can’t find the SOLR server, but it doesn’t seem to be easily reproducible.
Check your vitro.local.solr.url property in runtime.properties in the VIVO home directory and ensure that it
’s pointing to your SOLR installation. When VIVO can find SOLR, I’m betting that the silly classgroups error will also go away.

Actually, turns out it’s not so difficult to reproduce. I just did a fresh installation of VIVO and after editing vitro.local.solr.url to a value of http://localhost:8080/errorvivosolr (a value that will result in a 404) it produced the same vClassGroups-related TemplateException on the home page that you observed. Changing the property back to http://localhost:8080/vivosolr restored the home page to its normal operation.
So, most likely, when you get VIVO connected to Solr the problem will go away. I’ve opened a bug in JIRA, as there should be better error handling when this happens: https://jira.duraspace.org/browse/VIVO-1549 .
