Compatibility with QGIS >= 3.16

[Guts]

A new development cycle is started from tomorrow. The first goal is to make this plugin compatible with QGIS version 3.16. This issue is a "hub" of others related to QGIS compatibility.

@gioman when you say "latest release", you mean that you downloaded it from GitHub https://github.com/BRGM/gml_application_schema_toolbox/releases/tag/1.2.1-beta1 ?

Because I've just tested also on Windows today and it's working:

@Guts
Thanks for the quick answer. I mean the new version that just appeared in the QGIS plugins repository.

[Guts]

@gioman to be sure, did you select the "Experimental plugin" installation option?

(sorry I'm on Windows today, specifically to test against this OS)

@Guts sorry for the noise, for some reason from here the plugin manager only had available 1.2, now the beta is available and installs ok. Thanks!

[Guts]

No worry @gioman, I'd rather have false positives than miss something 😉 .

And this is a beta so it's still unstable so feel free to test and report or update some of issues 🎟️ .

[gioman]

@Guts thanks Julien

As start I can say that I was able to import GML file like http://inspire.ine.pt/AD/atom/gml/Addresses_4801_EPSG4258.zip (a sample of address from Portugal, following the INSPIRE data model) which never worked with previous release, if I recall correctly.

While navigating trough the tables and relations at some point I got a python error

Traceback (most recent call last):

RuntimeError: Network problem when downloading #PT.INE.ADD.AUN.AC25.PT

I also noticed that when opening the tables is asked "Python macros are currently disabled. Do you allow this macro to run?" and selecting "yes" works, but "don't ask anymore" which I expected to be automatic "yes" does not (seems is an automatic "no" instead). Maybe this is a QGIS issue?

Also seen this, which does not seems right:

[Guts]

@gioman Thank you for testing again! The first step was to make the plugin properly installable on QGIS 3.16 (and 3.12, 3.14).

Could you please create a dedicated ticket for each issue with maximum details (screenshots, etc.) as you did here? It'll help us to track on them.

@Guts done, but what about

this is QGIS or plugin problem?

[Guts]

I close here. I'll keep in touch about related issues.

[gioman]

ok.
