Description

On previous versions of QGIS I was able to import entire layer groups and their layers and symbology from other project files. Now when I do the same I get the layer names in the layer tree, but nothing appears.

It does work when I select a specific layer from the parent project file, but it does not when I want embed an entire layer group.

Hi, can you please add some minimal projects, so it is easier for people here to reproduce?

You could either add some tiny datasets, or else work with online services?

#4 Updated by Etiënne Thomassen over 1 year ago

I have enclosed a project file and a geopackage with 3 tables which are referenced from the project file.

Thanks to making these files, I now have additional feedback. I added screenshots of the steps I take.

Remarks:
- embedding layers from another project does not preserve the order of the layer(groups)
- layer groups embedded from another project are inactive after importing
- activating them does not make them visible
- moving a layer group seems to activate them and enables me to either make them visible. Or they appear after moving them when I already activated the layer

HTH!

Added feedback a few days ago, but I think I also need to set the status to 'open'?

#6 Updated by Jan Lippmann over 1 year ago

i can confirm. embedded layer and groups from other projects appears in the project (layertree) in which the groups/layer loaded in, BUT no layer data and no symbology appear. no embedded layer appear in the snap options.

affected version is 3.0.1

this problem do not accure with actual master.

can someone else confirm that issue? i think it's a regression and should be fixed in the next point release 3.0.2

thanks! :-)
