ILIAS-Version: v7.11 2022-06-29

a) When "Multiple Inputs" is deactivated: When clicking on "Hide/Show Results" not yet sent answers get erased (see first part of screencast).

b) When "Multiple Inputs" is activated (see second part of screencast):

After starting the LiveVoting by clicking on "Vote" students can't write an answer because the "+"-Button is not shown. It does appear only when students reload their browser

Error message when opening live voting survey

Dear live-voting-supportteam,
we have installed the live voting plugin in our Ilias learning platform
because we would like to use it.
Creating the questions and issuing the QR code works well. However, you
cannot access the survey with this code - not even after it has been
started. Here comes the error message:
Class 'ILIAS\GlobalScreen\Provider\PluginProviderCollection' not found

0029292: High database load caused by a LiveVoting select query

@kzimmermannfhms (aus Mantis verschoben)

Since about 1 hour, we are observing a unusually high server load on the Mariadb machine. The general response times of ILIAS is satisfactory, but a bit slower than usual. Not many users are logged in.

An investigation with Jet Profiler indicates that the server is busy with a lot of these queries (see attached screenshot):
SELECT rep_robj_xlvo_config_n.* FROM rep_robj_xlvo_config_n WHERE rep_robj_xlvo_config_n.pin = 'ILVM'

Is it possible to optimize the query and thus improve the performance?

Additional info: today we have same behaviour again.
There are many slow queries, all of them like this:
SELECT rep_robj_xlvo_config_n.* FROM rep_robj_xlvo_config_n WHERE rep_robj_xlvo_config_n.pin = 'UCKV'

Default RewriteRule does not work

The default RewriteRule, as stated in the README and documentation, does not work. First, the URL should be relative to the base URL:

RewriteRule ^/vote([|/|/0-9]*)$ /Customizing/global/plugins/Services/Repository/RepositoryObject/LiveVoting/pin.php?pin=$1 [L]

Notice the extra slashes before "vote" and "Customizing". Second, the Rule does not handle links with "pin" as GET parameter, but that's what the links in the QR fields contain. So a correct RewriteRule would look like this:

RewriteRule ^/vote(\?pin=[0-9]*)?$ /Customizing/global/plugins/Services/Repository/RepositoryObject/LiveVoting/pin.php$1 [L]

DatabaseDetector.php raises Exception in ILIAS 7-26 & v2023.01.26

When creating a new LiveVoting object an ilias error messages is thrown. The content of the exception is as follows:
