Hi,
I just migrated to primefaces 14.0.0 by changing the version in the dependency section of my project POM file. but I get the following :
```
StandardWrapperValve[Faces Servlet]: Servlet.service() for servlet Faces Servlet threw exception
java.lang.ClassNotFoundException: org.primefaces.expression.SearchExpressionFacade
```
This project uses California-5.1.0 template.
Any help please!
