Map composer. "Lock style for layers" setting ignored by Legend element in complex projects.

erydit commented 11 months ago

What is the bug or the crash?

In some complex projects "Lock style for layers" setting of the Map Item ignores. I attached an example project: example.zip

Steps to reproduce the issue

Extract example.zip and open the example folder.
Open the project qproj.qgz
Notice that the layer "FieldBorders" have the active style "Style_1".
Open the "Map_1". This layout was configured to use Style_2, and saved with the "Lock style for layers" property checked. And the Map looks as expected and uses Style_2. But in the Legend the Item FieldBorders is decorated as the Style_1.
OK, Return to the map view and select "Style_2" in the style properties of the FieldBorders layer. And open the Map_1 layout again. Now one of the Items looks as expected, and another use wrong style.
Uncheck and check again "Lock style for layers" to reload all styles of the Map. Now the Second Legent item use Style_2 .
Save the layout with the current settings. Select "Style_1" for the FieldBorders layer. Save and close the project.
Open the project again. And open Map_1 layout. And again the Legend looks wrong and uses the style that is active in the mapview despite that we saved the layout with the Style_2 in the 6 and 7 steps.

The realy bad thing about that bug is that a cant use ">qgis_process run native:atlaslayouttopdf ..." to render several layouts because some of them would be decorated in the wrong styles.

Use map theme in the meantime to lock your map rendering

@DelazJ Thank you for the advice! Map themes are indeed better way to organize styles and layers for the layouts. And they helped with the current issue.
