Hello,
I just update my b4j to v.7.
Now my project returns the following error while loading main layout

B4X:
MainForm.RootPane.LoadLayout("main") 'Load the layout file.
java.lang.RuntimeException: java.lang.NoClassDefFoundError: anywheresoftware/b4a/objects/ConcreteViewWrapper
the project use xCustomListView, I remove the old xCustomListView lib and recompile project.

What i'm missing?

Is it possible the layout is still referring to the old xCustomListView control?

Maybe you need to delete it from the layout file and then add it again which should force it use the new one.
