B4J Question error executing program after b4j 7 update

[fabton1963]

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

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?

Can you post the full error message? You shouldn't remove the library. Remove the class module named CustomListView.

Does it happen with all projects? Which version of Java are you using?

Worth reinstalling B4J in a new folder.

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.
