I upgraded a system (which was built a few years ago by another developer) from Vaadin 14 to Vaadin 23.5.4. I then also had to upgrade the dependency for twincolselect (with groupId org.vaadin.tatu) to the latest version, 3.2.0. But this exception then comes:
java.lang.ClassNotFoundException: com.vaadin.flow.component.html.NativeLabel TwinColSelect
at org.vaadin.tatu.TwinColSelect.<init>(TwinColSelect.java:146)
It comes when the TwinColSelect is created in our code:
databasesSelect = new TwinColSelect<>();
org.vaadin.tatu.TwinColSelect is imported and used. How can this be solved?
2.X.X (2.7.0 is the latest) is the correct version for Vaadin 23. The version you are using is for Vaadin 24.
Vaadin 24+
Vaadin 23 in 2.7.0
Vaadin 21 in 2.0.0
Vaadin 14 in 1.9.1
