<p>Hi Etienne,</p>
<p>I have now upgraded desktop and server to 3.18.1 and the latest
Lizmap 3.4.3, and also updated the Lizmap plugin. Still the same
problem:</p>
<p>The Lizmap popups do not show the children from the relations,
although ticked and published in WFS. And Dataviz does not show
the charts any more. The chart header briefly pops up and the
chart is not shown.</p>
<p>I guess it has something to do with the relations set up in the
QGIS project and my project is valid. So something has changed
between 2.16 and 2.18 or any subversions in between?</p>
<p>I also checked the "popupDisplayChildren": "True" in the .cfg and
the relation in the .qgs...all seem to be fine.</p>
<p>Any ideas?</p>
<p>Immo</p>

<div>It's not linked to your issue directly, but QGIS Server
3.16 might not read correctly a QGS file made with QGIS
Desktop 3.18. So some configs might be unread/lost by the
server. Always keep the same version.<br>

<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>
