I have a follow up to #348 and updated my reproduction project at https://codeberg.org/Til7701/java-gi-inheritance-bug

Firstly, when setting a property from a template in an instance of a class that is extending a Java implementation, it fails with object of type de.til.A is not an instance of de.til.B which you should see when running the example in the current state.

If you remove the line <property name="mode">discrete</property> in window.ui it can build the object from the template, but fails to put the instance into the field in the AppWindow giving the following message: java-gi-CRITICAL **: 20:32:49.332: Cannot get template child b in class de.til.AppWindow: Can not set de.til.B field de.til.AppWindow.b to de.til.A

I found the cause of the issue; thanks again for reporting this.

If you want a release for this soon, let me know, I can push a snapshot or minor release.
