Hi,  
I have implemented a custom structure view (alt+7) for custom files and it works as expected. But the file structure popup (ctrl+F12) always shows “Structure is empty”.

### **What I did**

1. Implemented and registered a  
**CustomStructureViewFactory** implements **PsiStructureViewFactory**  
along with  
**CustomStructureViewModel** extends **StructureViewModelBase** implements **StructureViewModel.ElementInfoProvider**  
and  
**CustomStructureViewElement** implements **StructureViewTreeElement**
2. Open a file that triggers the **CustomStructureViewFactory**
3. Open the **structure view** (alt+7) and see that it works
4. Open the **file structure popup** (ctrl+F12) and see “Structure is empty”

### Expected result:

If the structure view is populated correctly with the desired elements, the file structure popup should be too.

### Actual result:

The file structure popup remains empty.

When debugging I can confirm that the methods **getPresentation()** and **getChildren()** in my **StructureViewTreeElement** class are being called when pressing ctrl+F12 and seemingly perform correctly.

What could be the issue? Am I missing a class or method I need to implement for the file structure popup to work?

I do see warnings and SEVERE flags in the log regarding StructureViewComponent.class (InvalidMirrorException) but unfortunately that does not tell me much.

Interesting. It’s a similar problem, but the other way around (structure view empty instead of popup). Unfortunately, disabling the logical structure via that registry key did not work for me.
