Render Layers as a Group not working with Themes in Layout #50391

Open baswein opened 2 years ago

baswein commented 2 years ago

What is the bug or the crash?

If you create a group and select the Render Layers as a Group option and then add that group to a Theme it renders fine in both the map view and the layout view. However if in the Layout you select Follow map theme and choose the theme with the Group the layers in the group will not be rendered.

Demo Data:
Mask Below Theme.zip

Steps to reproduce the issue

  1. Create a new map and add a layer.
  2. Add the layer to a group.
  3. In the Group Styling set to Render Layer as a Group
  4. Create a Theme with the group and layer on.
  5. See that the layer is visible
  6. Create a layout and add a map.
  7. See that the layer is visible
  8. Set the Layout Map to Follow Map Theme with the theme set to (none)
  9. See the layer is visible
  10. Set the Theme to the theme you created
  11. See that the layer disappears

Confirmed. Quite annoying. A workaround until #51358 is fixed is to just uncheck the "render layers as a group" box and update the layout: the symbology still applies with the map theme and group constraint.
