[Question]: Warning - Many layers next to each other having different filters.

[aeduard]

What is the question? (in English)

I've read the Help about the checks, and I understand that in many situations it is better to not filter the layer and use the checkboxes. But still, sometimes I want 2 completely new layer from one table, eg. for different popups or other behavior. Or to set visibility differently at map loading.
Right now I can live with this error, as it displays only for admins, but I would like to know the reasoning behind.

Yes, I think we got the discussion with @mdouchin and we have some corner case about this check.

As a "quick workaround", you can do :

l = iface.activeLayer()
l.setCustomProperty("lizmap-plugin-skip-duplicated-layer", "yes")

Side note :

to set visibility differently at map loading.

This would be nice to implement as well, if you want. To read checked categories from the project.

Do you have an idea how to improve this check ?
