<p>Hi,</p>
<p>reverting to 3.10 will be difficult as the QGIS server is on an
external server on which I have little control. But maybe I must
mention that I am on Desktop 3.18 and the server on 3.16. I could
maybe go back to the LTR desktop and see what happens.</p>
<p>But also during the process I upgraded the Lizmap plugin...not
sure whether that made a difference. But I also noticed that the
"display children" in the popup does not work (it also used to
work). So somewhere there is a problem with detecting the
relationship?</p>
<p>I will try a few things, including updating the server and
provide feedback if I find anything worth noting.</p>

<p>Hi All,<br>
</p>
<p>My Setup:</p>
<ol>
<li>Lizmap 3.4.0</li>
<li>QGIS Server 3.16</li>
<li>All on Linux Server (not sure which one, offsite)</li>
<li>All spatial and table data in PosgreSQL<br>
</li>
</ol>
<p>I had a Dataviz set up with a bar chart for monthly rainfall
[mm] to display in the popup by clicking on a rainfall station
on the map. First I only had 3 sites which worked fine. Then I
added another four sites and now the chart header briefly
flashes and disappears again.</p>
<p>The rainfall station table is the master and the rainfall
readings are in a detail table (1-N) with 4 fields...ID,
site_id, date, reading and the relation set up with the
Rainfall station table's site_id. The readings are 1 per month
(monthly rainfall), so in Dataviz the X is the date field and
the Y is the reading field. There are about 3700 readings
(about 400 to 700 per site). Is there any limitation on that?
Why did it work with 3 sites and not with the seven? But now
even when reverting to the 3 sites it does not work any more.
Is that a cache problem? The detail table with the rainfall
readings is ticked in the WFS QGIS Server setup and the whole
project is valid.<br>
</p>
<p>It seems to be a problem with the relation (maybe???), but in
QGIS info tool the relations show fine (the detail data is
there).</p>
<p>This is quite frustrating.</p>
<p>Regards<br>
